AWK(1P) + + + +PROLOG + This manual page is part of the POSIX Programmer's Man- + ual. The Linux implementation of this interface may + differ (consult the corresponding Linux manual page for + details of Linux behavior), or the interface may not be + implemented on Linux. + +NAME + awk - pattern scanning and processing language + +SYNOPSIS + awk [-F ERE][-v assignment] ... program [argument ...] + + awk [-F ERE] -f progfile ... [-v assignment] ...[argu- + ment ...] + + +DESCRIPTION + The awk utility shall execute programs written in the + awk programming language, which is specialized for tex- + tual data manipulation. An awk program is a sequence of + patterns and corresponding actions. When input is read + that matches a pattern, the action associated with that + pattern is carried out. + + Input shall be interpreted as a sequence of records. By + default, a record is a line, less its terminating , but this can be changed by using the RS built-in + variable. Each record of input shall be matched in turn + against each pattern in the program. For each pattern + matched, the associated action shall be executed. + + The awk utility shall interpret each input record as a + sequence of fields where, by default, a field is a + string of non- s. This default white-space field + delimiter can be changed by using the FS built-in vari- + able or -F ERE. The awk utility shall denote the first + field in a record $1, the second $2, and so on. The sym- + bol $0 shall refer to the entire record; setting any + other field causes the re-evaluation of $0. Assigning to + $0 shall reset the values of all other fields and the NF + built-in variable. + +OPTIONS + The awk utility shall conform to the Base Definitions + volume of IEEE Std 1003.1-2001, Section 12.2, Utility + Syntax Guidelines. + + The following options shall be supported: + + -F ERE + Define the input field separator to be the + extended regular expression ERE, before any input + is read; see Regular Expressions . + + -f progfile + Specify the pathname of the file progfile con- + taining an awk program. If multiple instances of + this option are specified, the concatenation of + the files specified as progfile in the order + specified shall be the awk program. The awk pro- + gram can alternatively be specified in the com- + mand line as a single argument. + + -v assignment + The application shall ensure that the assignment + argument is in the same form as an assignment + operand. The specified variable assignment shall + occur prior to executing the awk program, includ- + ing the actions associated with BEGIN patterns + (if any). Multiple occurrences of this option can + be specified. + + +OPERANDS + The following operands shall be supported: + + program + If no -f option is specified, the first operand + to awk shall be the text of the awk program. The + application shall supply the program operand as a + single argument to awk. If the text does not end + in a , awk shall interpret the text as + if it did. + + argument + Either of the following two types of argument can + be intermixed: + + file + A pathname of a file that contains the input to + be read, which is matched against the set of pat- + terns in the program. If no file operands are + specified, or if a file operand is '-', the stan- + dard input shall be used. + + assignment + An operand that begins with an underscore or + alphabetic character from the portable character + set (see the table in the Base Definitions volume + of IEEE Std 1003.1-2001, Section 6.1, Portable + Character Set), followed by a sequence of under- + scores, digits, and alphabetics from the portable + character set, followed by the '=' character, + shall specify a variable assignment rather than a + pathname. The characters before the '=' represent + the name of an awk variable; if that name is an + awk reserved word (see Grammar ) the behavior is + undefined. The characters following the equal + sign shall be interpreted as if they appeared in + the awk program preceded and followed by a dou- + ble-quote ( ' )' character, as a STRING token + (see Grammar ), except that if the last character + is an unescaped backslash, it shall be inter- + preted as a literal backslash rather than as the + first character of the sequence "\"" . The vari- + able shall be assigned the value of that STRING + token and, if appropriate, shall be considered a + numeric string (see Expressions in awk ), the + variable shall also be assigned its numeric + value. Each such variable assignment shall occur + just prior to the processing of the following + file, if any. Thus, an assignment before the + first file argument shall be executed after the + BEGIN actions (if any), while an assignment after + the last file argument shall occur before the END + actions (if any). If there are no file arguments, + assignments shall be executed before processing + the standard input. + + + +STDIN + The standard input shall be used only if no file + operands are specified, or if a file operand is '-' ; + see the INPUT FILES section. If the awk program contains + no actions and no patterns, but is otherwise a valid awk + program, standard input and any file operands shall not + be read and awk shall exit with a return status of zero. + +INPUT FILES + Input files to the awk program from any of the following + sources shall be text files: + + * Any file operands or their equivalents, achieved by + modifying the awk variables ARGV and ARGC + + + * Standard input in the absence of any file operands + + + * Arguments to the getline function + + + Whether the variable RS is set to a value other than a + or not, for these files, implementations shall + support records terminated with the specified separator + up to {LINE_MAX} bytes and may support longer records. + + If -f progfile is specified, the application shall + ensure that the files named by each of the progfile + option-arguments are text files and their concatenation, + in the same order as they appear in the arguments, is an + awk program. + +ENVIRONMENT VARIABLES + The following environment variables shall affect the + execution of awk: + + LANG Provide a default value for the internationaliza- + tion variables that are unset or null.

Each pattern in the program then shall + be evaluated in the order of occurrence, and the action + associated with each pattern that matches the current + record executed.

Note the difference between: + + + chmod a-w file + + which removes all write permissions, and: + + + chmod -- -w file + + which removes write permissions that would be allowed if + file was created with the same umask. + + Conforming applications should never assume that they + know how the set-user-ID and set-group-ID bits on direc- + tories are interpreted. + +EXAMPLES +Mode Results +a+= Equivalent to a+, a=; clears all file mode bits. +go+-w Equivalent to go+, go- w; clears group and other write bits. +g=o-w Equivalent to g= o, g- w; sets group bit to match other bits and then clears group write bit. +g-r+w Equivalent to g- r, g+ w; clears group read bit and sets group write bit. +uo=g Sets owner bits to match group bits and sets other bits to match group bits. + +RATIONALE + The functionality of chmod is described substantially + through references to concepts defined in the System + Interfaces volume of IEEE Std 1003.1-2001. In this way, + there is less duplication of effort required for + describing the interactions of permissions. However, the + behavior of this utility is not described in terms of + the chmod() function from the System Interfaces volume + of IEEE Std 1003.1-2001 because that specification + requires certain side effects upon alternate file access + control mechanisms that might not be appropriate, + depending on the implementation. + + Implementations that support mandatory file and record + locking as specified by the 1984 /usr/group standard + historically used the combination of set-group-ID bit + set and group execute bit clear to indicate mandatory + locking. This condition is usually set or cleared with + the symbolic mode perm symbol l instead of the perm sym- + bols s and x so that the mandatory locking mode is not + changed without explicit indication that that was what + the user intended. Therefore, the details on how the + implementation treats these conditions must be defined + in the documentation. This volume of + IEEE Std 1003.1-2001 does not require mandatory locking + (nor does the System Interfaces volume of + IEEE Std 1003.1-2001), but does allow it as an exten- + sion. However, this volume of IEEE Std 1003.1-2001 does + require that the ls and chmod utilities work consis- + tently in this area. If ls -l file indicates that the + set-group-ID bit is set, chmod g-s file must clear it + (assuming appropriate privileges exist to change modes). + + The System V and BSD versions use different exit status + codes. Some implementations used the exit status as a + count of the number of errors that occurred; this prac- + tice is unworkable since it can overflow the range of + valid exit status values. This problem is avoided here + by specifying only 0 and >0 as exit values. + + The System Interfaces volume of IEEE Std 1003.1-2001 + indicates that implementation-defined restrictions may + cause the S_ISUID and S_ISGID bits to be ignored. This + volume of IEEE Std 1003.1-2001 allows the chmod utility + to choose to modify these bits before calling chmod() + (or some function providing equivalent capabilities) for + non-regular files. Among other things, this allows + implementations that use the set-user-ID and set-group- + ID bits on directories to enable extended features to + handle these extensions in an intelligent manner. + + The X perm symbol was adopted from BSD-based systems + because it provides commonly desired functionality when + doing recursive ( -R option) modifications. Similar + functionality is not provided by the find utility.

Neither the System V nor BSD + sum algorithm was selected. Since each of these was dif- + ferent and each was the default behavior on those sys- + tems, no realistic compromise was available if either + were selected-some set of historical applications would + break. Therefore, the name was changed to cksum. + Although the historical sum commands will probably con- + tinue to be provided for many years, programs designed + for portability across systems should use the new name. + + The algorithm selected is based on that used by the + ISO/IEC 8802-3:1996 standard (Ethernet) for the frame + check sequence field. The algorithm used does not match + the technical definition of a checksum; the term is used + for historical reasons. The length of the file is + included in the CRC calculation because this parallels + inclusion of a length field by Ethernet in its CRC, but + also because it guards against inadvertent collisions + between files that begin with different series of zero + octets. The chance that two different files produce + identical CRCs is much greater when their lengths are + not considered. Keeping the length and the checksum of + the file itself separate would yield a slightly more + robust algorithm, but historical usage has always been + that a single number (the checksum as printed) repre- + sents the signature of the file. It was decided that + historical usage was the more important consideration. + + Early proposals contained modifications to the Ethernet + algorithm that involved extracting table values whenever + an intermediate result became zero.

The + original -r flag, for historic reasons, does not handle + special files any differently from regular files, but + always reads the file and copies its contents. This has + obvious problems in the presence of special file types; + for example, character devices, FIFOs, and sockets. The + -R option is intended to recreate the file hierarchy and + the -r option supports historical practice. It was + anticipated that a future version of this volume of + IEEE Std 1003.1-2001 would deprecate the -r option, and + for that reason, there has been no attempt to fix its + behavior with respect to FIFOs or other file types where + copying the file is clearly wrong. However, some imple- + mentations support -r with the same abilities as the -R + defined in this volume of IEEE Std 1003.1-2001. To + accommodate them as well as systems that do not, the + differences between -r and -R are implementation- + defined. Implementations may make them identical. The -r + option is marked obsolescent. + + The set-user-ID and set-group-ID bits are explicitly + cleared when files are created. This is to prevent users + from creating programs that are set-user-ID or set- + group-ID to them when copying files or to make set-user- + ID or set-group-ID files accessible to new groups of + users. For example, if a file is set-user-ID and the + copy has a different group ID than the source, a new + group of users has execute permission to a set-user-ID + program than did previously. In particular, this is a + problem for superusers copying users' trees. + +EXAMPLES + None. + +RATIONALE + The -i option exists on BSD systems, giving applications + and users a way to avoid accidentally removing files + when copying. Although the 4.3 BSD version does not + prompt if the standard input is not a terminal, the + standard developers decided that use of -i is a request + for interaction, so when the destination path exists, + the utility takes instructions from whatever responds on + standard input. + + The exact format of the interactive prompts is unspeci- + fied. Only the general nature of the contents of prompts + are specified because implementations may desire more + descriptive prompts than those used on historical imple- + mentations. Therefore, an application using the -i + option relies on the system to provide the most suitable + dialog directly with the user, based on the behavior + specified. + + The -p option is historical practice on BSD systems, + duplicating the time of last data modification and time + of last access. This volume of IEEE Std 1003.1-2001 + extends it to preserve the user and group IDs, as well + as the file permissions. This requirement has obvious + problems in that the directories are almost certainly + modified after being copied. This volume of + IEEE Std 1003.1-2001 requires that the modification + times be preserved. The statement that the order in + which the characteristics are duplicated is unspecified + is to permit implementations to provide the maximum + amount of security for the user. Implementations should + take into account the obvious security issues involved + in setting the owner, group, and mode in the wrong order + or creating files with an owner, group, or mode differ- + ent from the final value. + + It is unspecified whether cp writes diagnostic messages + when the user and group IDs cannot be set due to the + widespread practice of users using -p to duplicate some + portion of the file characteristics, indifferent to the + duplication of others. Historic implementations only + write diagnostic messages on errors other than [EPERM]. + + The -r option is historical practice on BSD and BSD- + derived systems, copying file hierarchies as opposed to + single files. This functionality is used heavily in + historical applications, and its loss would signifi- + cantly decrease consensus. The -R option was added as a + close synonym to the -r option, selected for consistency + with all other options in this volume of + IEEE Std 1003.1-2001 that do recursive directory + descent. + + When a failure occurs during the copying of a file hier- + archy, cp is required to attempt to copy files that are + on the same level in the hierarchy or above the file + where the failure occurred. It is unspecified if cp + shall attempt to copy files below the file where the + failure occurred (which cannot succeed in any case). + + Permissions, owners, and groups of created special file + types have been deliberately left as implementation- + defined. This is to allow systems to satisfy special + requirements (for example, allowing users to create + character special devices, but requiring them to be + owned by a certain group). In general, it is strongly + suggested that the permissions, owner, and group be the + same as if the user had run the historical mknod, ln, or + other utility to create the file. It is also probable + that additional privileges are required to create block, + character, or other implementation-defined special file + types. + + Additionally, the -p option explicitly requires that all + set-user-ID and set-group-ID permissions be discarded if + any of the owner or group IDs cannot be set. This is to + keep users from unintentionally giving away special + privilege when copying programs. + + When creating regular files, historical versions of cp + use the mode of the source file as modified by the file + mode creation mask. Other choices would have been to use + the mode of the source file unmodified by the creation + mask or to use the same mode as would be given to a new + file created by the user (plus the execution bits of the + source file) and then modify it by the file mode cre- + ation mask. In the absence of any strong reason to + change historic practice, it was in large part retained. + + When creating directories, historical versions of cp use + the mode of the source directory, plus read, write, and + search bits for the owner, as modified by the file mode + creation mask. This is done so that cp can copy trees + where the user has read permission, but the owner does + not. A side effect is that if the file creation mask + denies the owner permissions, cp fails. Also, once the + copy is done, historical versions of cp set the permis- + sions on the created directory to be the same as the + source directory, unmodified by the file creation mask. + + This behavior has been modified so that cp is always + able to create the contents of the directory, regardless + of the file creation mask. After the copy is done, the + permissions are set to be the same as the source direc- + tory, as modified by the file creation mask. This latter + change from historical behavior is to prevent users from + accidentally creating directories with permissions + beyond those they would normally set and for consistency + with the behavior of cp in creating files. + + It is not a requirement that cp detect attempts to copy + a file to itself; however, implementations are strongly + encouraged to do so. Historical implementations have + detected the attempt in most cases. + + There are two methods of copying subtrees in this volume + of IEEE Std 1003.1-2001. The other method is described + as part of the pax utility (see pax ). Both methods are + historical practice. The cp utility provides a simpler, + more intuitive interface, while pax offers a finer gran- + ularity of control. Each provides additional functional- + ity to the other; in particular, pax maintains the hard- + link structure of the hierarchy, while cp does not. It + is the intention of the standard developers that the + results be similar (using appropriate option combina- + tions in both utilities). The results are not required + to be identical; there seemed insufficient gain to + applications to balance the difficulty of implementa- + tions having to guarantee that the results would be + exactly identical. + + The wording allowing cp to copy a directory to implemen- + tation-defined file types not specified by the System + Interfaces volume of IEEE Std 1003.1-2001 is provided so + that implementations supporting symbolic links are not + required to prohibit copying directories to symbolic + links.

Some of them can contain s + in some locales, so it may be difficult to use the for- + mat shown in standard output for parsing the output of + date in those locales. + + The range of values for %S extends from 0 to 60 seconds + to accommodate the occasional leap second. + + Although certain of the conversion specifiers in the + POSIX locale (such as the name of the month) are shown + with initial capital letters, this need not be the case + in other locales. Programs using these fields may need + to adjust the capitalization if the output is going to + be used at the beginning of a sentence. + + The date string formatting capabilities are intended for + use in Gregorian-style calendars, possibly with a dif- + ferent starting year (or years). The %x and %c conver- + sion specifications, however, are intended for local + representation; these may be based on a different, non- + Gregorian calendar. + + The %C conversion specification was introduced to allow + a fallback for the %EC (alternative year format base + year); it can be viewed as the base of the current sub- + division in the Gregorian calendar. The century number + is calculated as the year divided by 100 and truncated + to an integer; it should not be confused with the use of + ordinal numbers for centuries (for example, "twenty- + first century".) Both the %Ey and %y can then be viewed + as the offset from %EC and %C , respectively. + + The E and O modifiers modify the traditional conversion + specifiers, so that they can always be used, even if the + implementation (or the current locale) does not support + the modifier. + + The E modifier supports alternative date formats, such + as the Japanese Emperor's Era, as long as these are + based on the Gregorian calendar system. Extending the E + modifiers to other date elements may provide an imple- + mentation-defined extension capable of supporting other + calendar systems, especially in combination with the O + modifier. + + The O modifier supports time and date formats using the + locale's alternative numerical symbols, such as Kanji or + Hindi digits or ordinal number representation. + + Non-European locales, whether they use Latin digits in + computational items or not, often have local forms of + the digits for use in date formats. This is not totally + unknown even in Europe; a variant of dates uses Roman + numerals for the months: the third day of September 1991 + would be written as 3.IX.1991. In Japan, Kanji digits + are regularly used for dates; in Arabic-speaking coun- + tries, Hindi digits are used. The %d , %e , %H , %I , %m + , %S , %U , %w , %W , and %y conversion specifications + always return the date and time field in Latin digits + (that is, 0 to 9). The %O modifier was introduced to + support the use for display purposes of non-Latin dig- + its. In the LC_TIME category in localedef, the optional + alt_digits keyword is intended for this purpose. As an + example, assume the following (partial) localedef + source: + + + alt_digits "";"I";"II";"III";"IV";"V";"VI";"VII";"VIII" \ + "IX";"X";"XI";"XII" + d_fmt "%e.%Om.%Y" + + With the above date, the command: + + + date "+%x" + + would yield 3.IX.1991.

It shall + read the input one block at a time, using the specified + input block size; it shall then process the block of + data actually returned, which could be smaller than the + requested block size. It shall apply any conversions + that have been specified and write the resulting data to + the output in blocks of the specified output block size. + If the bs= expr operand is specified and no conversions + other than sync, noerror, or notrunc are requested, the + data returned from each input block shall be written as + a separate output block; if the read returns less than a + full block and the sync conversion is not specified, the + resulting output block shall be the same size as the + input block. If the bs= expr operand is not specified, + or a conversion other than sync, noerror, or notrunc is + requested, the input shall be processed and collected + into full-sized output blocks until the end of the input + is reached. + + The processing order shall be as follows: + + An input block is read. + + If the input block is shorter than the specified input + block size and the sync conversion is specified, null + bytes shall be appended to the input data up to the + specified size. (If either block or unblock is also + specified, s shall be appended instead of null + bytes.) The remaining conversions and output shall + include the pad characters as if they had been read from + the input. + + If the bs= expr operand is specified and no conversion + other than sync or noerror is requested, the resulting + data shall be written to the output as a single block, + and the remaining steps are omitted. + + If the swab conversion is specified, each pair of input + data bytes shall be swapped.

(If the size + of the seek plus the size of the input file is + less than the previous size of the output file, + the output file shall be shortened by the copy.) + + ibs=expr + Specify the input block size, in bytes, by expr + (default is 512). + + obs=expr + Specify the output block size, in bytes, by expr + (default is 512). + + bs=expr + Set both input and output block sizes to expr + bytes, superseding ibs= and obs=. If no conver- + sion other than sync, noerror, and notrunc is + specified, each input block shall be copied to + the output as a single block without aggregating + short blocks. + + cbs=expr + Specify the conversion block size for block and + unblock in bytes by expr (default is zero).

The ASCII and EBCDIC conversions specified for the + dd utility perform conversions for the version specified + by the tables. + +EXAMPLES + The following command: + + + dd if=/dev/rmt0h of=/dev/rmt1h + + copies from tape drive 0 to tape drive 1, using a common + historical device naming convention. + + The following command: + + + dd ibs=10 skip=1 + + strips the first 10 bytes from standard input. + + This example reads an EBCDIC tape blocked ten 80-byte + EBCDIC card images per block into the ASCII file x: + + + dd if=/dev/tape of=x ibs=800 cbs=80 conv=ascii,lcase + +RATIONALE + The OPTIONS section is listed as "None" because there + are no options recognized by historical dd utilities. + Certainly, many of the operands could have been designed + to use the Utility Syntax Guidelines, which would have + resulted in the classic hyphenated option letters. In + this version of this volume of IEEE Std 1003.1-2001, dd + retains its curious JCL-like syntax due to the large + number of applications that depend on the historical + implementation. + + A suggested implementation technique for conv= noerror, + sync is to zero (or -fill, if blocking or + unblocking) the input buffer before each read and to + write the contents of the input buffer to the output + even after an error. In this manner, any data trans- + ferred to the input buffer before the error was detected + is preserved. Another point is that a failed read on a + regular file or a disk generally does not increment the + file offset, and dd must then seek past the block on + which the error occurred; otherwise, the input error + occurs repetitively. When the input is a magnetic tape, + however, the tape normally has passed the block contain- + ing the error when the error is reported, and thus no + seek is necessary. + + The default ibs= and obs= sizes are specified as 512 + bytes because there are historical (largely portable) + scripts that assume these values. If they were left + unspecified, unusual results could occur if an implemen- + tation chose an odd block size. + + Historical implementations of dd used creat() when pro- + cessing of= file. This makes the seek= operand unusable + except on special files. The conv= notrunc feature was + added because more recent BSD-based implementations use + open() (without O_TRUNC) instead of creat(), but they + fail to delete output file contents after the data + copied. + + The w multiplier (historically meaning word), is used in + System V to mean 2 and in 4.2 BSD to mean 4. Since word + is inherently non-portable, its use is not supported by + this volume of IEEE Std 1003.1-2001. + + Standard EBCDIC does not have the characters '[' and ']' + . The values used in the table are taken from a common + print train that does contain them. Other than those + characters, the print train values are not filled in, + but appear to provide some of the motivation for the + historical choice of translations reflected here. + + The Standard EBCDIC table provides a 1:1 translation for + all 256 bytes. + + The IBM EBCDIC table does not provide such a transla- + tion. The marked cells in the tables differ in such a + way that: + + EBCDIC 0112 ( 'cent' ) and 0152 (broken pipe) do not + appear in the table. + + EBCDIC 0137 ( 'not' ) translates to/from ASCII 0236 ( + '^' ). In the standard table, EBCDIC 0232 (no graphic) + is used. + + EBCDIC 0241 ( '~' ) translates to/from ASCII 0176 ( '~' + ). In the standard table, EBCDIC 0137 ( 'not' ) is used. + + 0255 ( '[' ) and 0275 ( ']' ) appear twice, once in the + same place as for the standard table and once in place + of 0112 ( 'cent' ) and 0241 ( '~' ). + + In net result: EBCDIC 0275 ( ']' ) displaced EBCDIC 0241 + ( '~' ) in cell 0345. + + That displaced EBCDIC 0137 ( 'not' ) in cell 0176. + + That displaced EBCDIC 0232 (no graphic) in cell + 0136. + + That replaced EBCDIC 0152 (broken pipe) in cell + 0313. + + EBCDIC 0255 ( '[' ) replaced EBCDIC 0112 ( 'cent' ). + + This translation, however, reflects historical practice + that (ASCII) '~' and 'not' were often mapped to each + other, as were '[' and 'cent' ; and ']' and (EBCDIC) '~' + . + + The cbs operand is required if any of the ascii, ebcdic, + or ibm operands are specified. For the ascii operand, + the input is handled as described for the unblock oper- + and except that characters are converted to ASCII before + the trailing s are deleted. For the ebcdic and + ibm operands, the input is handled as described for the + block operand except that the characters are converted + to EBCDIC or IBM EBCDIC after the trailing s are + added. + + The block and unblock keywords are from historical BSD + practice. + + The consistent use of the word record in standard error + messages matches most historical practice. An earlier + version of System V used block, but this has been + updated in more recent releases. + + Early proposals only allowed two numbers separated by x + to be used in a product when specifying bs=, cbs=, ibs=, + and obs= sizes. This was changed to reflect the histori- + cal practice of allowing multiple numbers in the product + as provided by Version 7 and all releases of System V + and BSD. + + A change to the swab conversion is required to match + historical practice and is the result of IEEE PASC + Interpretations 1003.2 #03 and #04, submitted for the + ISO POSIX-2:1993 standard. + + A change to the handling of SIGINT is required to match + historical practice and is the result of IEEE PASC + Interpretation 1003.2 #06 submitted for the + ISO POSIX-2:1993 standard. + +FUTURE DIRECTIONS + None. + +SEE ALSO + Utility Description Defaults , sed , tr + +COPYRIGHT + Portions of this text are reprinted and reproduced in + electronic form from IEEE Std 1003.1, 2003 Edition, + Standard for Information Technology -- Portable Operat- + ing System Interface (POSIX), The Open Group Base Speci- + fications Issue 6, Copyright (C) 2001-2003 by the Insti- + tute of Electrical and Electronics Engineers, Inc and + The Open Group.

The value 127 was chosen because it + is not commonly used for other meanings; most utilities + use small values for "normal error conditions" and the + values above 128 can be confused with termination due to + receipt of a signal. The value 126 was chosen in a simi- + lar manner to indicate that the utility could be found, + but not invoked. Some scripts produce meaningful error + messages differentiating the 126 and 127 cases. The dis- + tinction between exit codes 126 and 127 is based on + KornShell practice that uses 127 when all attempts to + exec the utility fail with [ENOENT], and uses 126 when + any attempt to exec the utility fails for any other rea- + son. + + Historical implementations of the env utility use the + execvp() or execlp() functions defined in the System + Interfaces volume of IEEE Std 1003.1-2001 to invoke the + specified utility; this provides better performance and + keeps users from having to escape characters with spe- + cial meaning to the shell.

Any expression can be placed within parentheses. Parentheses can be nested to a depth of {EXPR_NEST_MAX}. +integer An argument consisting only of an (optional) unary minus followed by digits. +string A string argument; see below. + + Matching Expression + The ':' matching operator shall compare the string + resulting from the evaluation of expr1 with the regular + expression pattern resulting from the evaluation of + expr2. Regular expression syntax shall be that defined + in the Base Definitions volume of IEEE Std 1003.1-2001, + Section 9.3, Basic Regular Expressions, except that all + patterns are anchored to the beginning of the string + (that is, only sequences starting at the first character + of a string are matched by the regular expression) and, + therefore, it is unspecified whether '^' is a special + character in that context. Usually, the matching opera- + tor shall return a string representing the number of + characters matched ( '0' on failure). Alternatively, if + the pattern contains at least one regular expression + subexpression "[\(...\)]" , the string corresponding to + "\1" shall be returned. + + String Operand + A string argument is an argument that cannot be identi- + fied as an integer argument or as one of the expression + operator symbols shown in the OPERANDS section. + + The use of string arguments length, substr, index, or + match produces unspecified results. + +EXIT STATUS + The following exit values shall be returned: + + 0 The expression evaluates to neither null nor + zero. + + 1 The expression evaluates to null or zero. + + 2 Invalid expression. + + >2 An error occurred. + + +CONSEQUENCES OF ERRORS + Default. + + The following sections are informative. + +APPLICATION USAGE + After argument processing by the shell, expr is not + required to be able to tell the difference between an + operator and an operand except by the value. If "$a" is + '=' , the command: + + + expr $a = '=' + + looks like: + + + expr = = = + + as the arguments are passed to expr (and they all may be + taken as the '=' operator). The following works reli- + ably: + + + expr X$a = X= + + Also note that this volume of IEEE Std 1003.1-2001 per- + mits implementations to extend utilities. The expr util- + ity permits the integer arguments to be preceded with a + unary minus. This means that an integer argument could + look like an option. Therefore, the conforming applica- + tion must employ the "--" construct of Guideline 10 of + the Base Definitions volume of IEEE Std 1003.1-2001, + Section 12.2, Utility Syntax Guidelines to protect its + operands if there is any chance the first operand might + be a negative integer (or any string with a leading + minus). + +EXAMPLES + The expr utility has a rather difficult syntax: + + Many of the operators are also shell control + operators or reserved words, so they have to be + escaped on the command line. + + Each part of the expression is composed of sepa- + rate arguments, so liberal usage of s is + required. For example: + Invalid Valid + + expr 1+2 expr 1 + 2 + expr "1 + 2" expr 1 + 2 + expr 1 + (2 * 3) expr 1 + \( 2 \* 3 \) + + In many cases, the arithmetic and string features pro- + vided as part of the shell command language are easier + to use than their equivalents in expr. Newly written + scripts should avoid expr in favor of the new features + within the shell; see Parameters and Variables and + Arithmetic Expansion . + + The following command: + + + a=$(expr $a + 1) + + adds 1 to the variable a. + + The following command, for "$a" equal to either + /usr/abc/file or just file: + + + expr $a : '.*/\(.*\)' \| $a + + returns the last segment of a pathname (that is, file). + Applications should avoid the character '/' used alone + as an argument; expr may interpret it as the division + operator. + + The following command: + + + expr "//$a" : '.*/\(.*\)' + + is a better representation of the previous example. The + addition of the "//" characters eliminates any ambiguity + about the division operator and simplifies the whole + expression. Also note that pathnames may contain charac- + ters contained in the IFS variable and should be quoted + to avoid having "$a" expand into multiple arguments. + + The following command: + + + expr "$VAR" : '.*' + + returns the number of characters in VAR. + +RATIONALE + In an early proposal, EREs were used in the matching + expression syntax. This was changed to BREs to avoid + breaking historical applications. + + The use of a leading circumflex in the BRE is unspeci- + fied because many historical implementations have + treated it as a special character, despite their system + documentation. For example: + + + expr foo : ^foo expr ^foo : ^foo + + return 3 and 0, respectively, on those systems; their + documentation would imply the reverse.

Applications can use this field to pass + directly to a user printout or prompt, but actions based + on its contents should generally be deferred, instead, + to the test utility. + + The output of ls (with the -l and related options) con- + tains information that logically could be used by utili- + ties such as chmod and touch to restore files to a known + state. However, this information is presented in a for- + mat that cannot be used directly by those utilities or + be easily translated into a format that can be used. A + character has been added to the end of the permissions + string so that applications at least have an indication + that they may be working in an area they do not under- + stand instead of assuming that they can translate the + permissions string into something that can be used. + Future issues or related documents may define one or + more specific characters to be used based on different + standard additional or alternative access control mecha- + nisms. + + As with many of the utilities that deal with filenames, + the output of ls for multiple files or in one of the + long listing formats must be used carefully on systems + where filenames can contain embedded white space.

The only limita- + tion on depth should be based on running out of physical + storage for keeping track of untraversed directories. + + The -1 (one) option was historically found in BSD and + BSD-derived implementations only. It is required in this + volume of IEEE Std 1003.1-2001 so that conforming appli- + cations might ensure that output is one entry per line, + even if the output is to a terminal. + + Generally, this volume of IEEE Std 1003.1-2001 is silent + about what happens when options are given multiple + times. In the cases of -C, -l, and -1, however, it does + specify the results of these overlapping options. Since + ls is one of the most aliased commands, it is important + that the implementation perform intuitively. For exam- + ple, if the alias were: + + + alias ls="ls -C" + + and the user typed ls -1, single-text-column output + should result, not an error. + + The BSD ls provides a -A option (like -a, but dot and + dot-dot are not written out). The small difference from + -a did not seem important enough to require both. + + Implementations may make -q the default for terminals to + prevent trojan horse attacks on terminals with special + escape sequences. This is not required because: + + Some control characters may be useful on some + terminals; for example, a system might write them + as "\001" or "^A" . + + Special behavior for terminals is not relevant to + applications portability. + + An early proposal specified that the optional alternate + access method flag had to be '+' if there was an alter- + nate access method used on the file or if there + was not. This was changed to be if there is not + and a single printable character if there is. This was + done for three reasons: + + There are historical implementations using characters + other than '+' . + + There are implementations that vary this character used + in that position to distinguish between various alter- + nate access methods in use. + + The standard developers did not want to preclude future + specifications that might need a way to specify more + than one alternate access method. + + Nonetheless, implementations providing a single alter- + nate access method are encouraged to use '+' . + + In an early proposal, the units used to specify the num- + ber of blocks occupied by files in a directory in an ls + -l listing were implementation-defined. This was because + BSD systems have historically used 1024-byte units and + System V systems have historically used 512-byte units. + It was pointed out by BSD developers that their system + has used 512-byte units in some places and 1024-byte + units in other places. (System V has consistently used + 512.) Therefore, this volume of IEEE Std 1003.1-2001 + usually specifies 512. Future releases of BSD are + expected to consistently provide 512 bytes as a default + with a way of specifying 1024-byte units where appropri- + ate. + + The field in the -l format is specified + only for the POSIX locale.

Applications which + make use of the st_ctime field may behave differently + with respect to renamed files unless they are designed + to allow for either behavior. + +EXAMPLES + If the current directory contains only files a (of any + type defined by the System Interfaces volume of + IEEE Std 1003.1-2001), b (also of any type), and a + directory c: + + + mv a b c + mv c d + + results with the original files a and b residing in the + directory d in the current directory. + +RATIONALE + Early proposals diverged from the SVID and BSD histori- + cal practice in that they required that when the desti- + nation path exists, the -f option is not specified, and + input is not a terminal, mv fails. This was done for + compatibility with cp. The current text returns to his- + torical practice. It should be noted that this is con- + sistent with the rename() function defined in the System + Interfaces volume of IEEE Std 1003.1-2001, which does + not require write permission on the target. + + For absolute clarity, paragraph (1), describing the + behavior of mv when prompting for confirmation, should + be interpreted in the following manner: + + + if (exists AND (NOT f_option) AND + ((not_writable AND input_is_terminal) OR i_option)) + + The -i option exists on BSD systems, giving applications + and users a way to avoid accidentally unlinking files + when moving others. When the standard input is not a + terminal, the 4.3 BSD mv deletes all existing destina- + tion paths without prompting, even when -i is specified; + this is inconsistent with the behavior of the 4.3 BSD cp + utility, which always generates an error when the file + is unwritable and the standard input is not a terminal. + The standard developers decided that use of -i is a + request for interaction, so when the destination path + exists, the utility takes instructions from whatever + responds to standard input. + + The rename() function is able to move directories within + the same file system. Some historical versions of mv + have been able to move directories, but not to a differ- + ent file system. The standard developers considered that + this was an annoying inconsistency, so this volume of + IEEE Std 1003.1-2001 requires directories to be able to + be moved even across file systems. There is no -R option + to confirm that moving a directory is actually intended, + since such an option was not required for moving direc- + tories in historical practice. Requiring the application + to specify it sometimes, depending on the destination, + seemed just as inconsistent. The semantics of the + rename() function were preserved as much as possible. + For example, mv is not permitted to "rename" files to or + from directories, even though they might be empty and + removable. + + Historic implementations of mv did not exit with a non- + zero exit status if they were unable to duplicate any + file characteristics when moving a file across file sys- + tems, nor did they write a diagnostic message for the + user. The former behavior has been preserved to prevent + scripts from breaking; a diagnostic message is now + required, however, so that users are alerted that the + file characteristics have changed. + + The exact format of the interactive prompts is unspeci- + fied. Only the general nature of the contents of prompts + are specified because implementations may desire more + descriptive prompts than those used on historical imple- + mentations. Therefore, an application not using the -f + option or using the -i option relies on the system to + provide the most suitable dialog directly with the user, + based on the behavior specified. + + When mv is dealing with a single file system and + source_file is a symbolic link, the link itself is moved + as a consequence of the dependence on the rename() func- + tionality, per the DESCRIPTION.

Since there is no error penalty + associated with guessing a number that is too high, + users without access to the system conformance document + (to see what limits are actually in place) could use the + historical 1 to 20 range or attempt to use very large + numbers if the job should be truly low priority. + + The nice value of a process can be displayed using the + command: + + + ps -o nice + + The command, env, nice, nohup, time, and xargs utilities + have been specified to use exit code 127 if an error + occurs so that applications can distinguish "failure to + find a utility" from "invoked utility exited with an + error indication". The value 127 was chosen because it + is not commonly used for other meanings; most utilities + use small values for "normal error conditions" and the + values above 128 can be confused with termination due to + receipt of a signal. The value 126 was chosen in a simi- + lar manner to indicate that the utility could be found, + but not invoked. Some scripts produce meaningful error + messages differentiating the 126 and 127 cases. The dis- + tinction between exit codes 126 and 127 is based on + KornShell practice that uses 127 when all attempts to + exec the utility fail with [ENOENT], and uses 126 when + any attempt to exec the utility fails for any other rea- + son. + +EXAMPLES + None. + +RATIONALE + Due to the text about the limits of the nice value being + implementation-defined, nice is not actually required to + change the nice value of the executed command; the lim- + its could be zero differences from the system default, + although the implementor is required to document this + fact in the conformance document. + + The 4.3 BSD version of nice does not check whether + increment is a valid decimal integer. The command nice + -x utility, for example, would be treated the same as + the command nice --1 utility. If the user does not have + appropriate privileges, this results in a "permission + denied" error. This is considered a bug. + + When a user without appropriate privileges gives a nega- + tive increment, System V treats it like the command nice + -0 utility, while 4.3 BSD writes a "permission denied" + message and does not run the utility. Neither was con- + sidered clearly superior, so the behavior was left + unspecified. + + The C shell has a built-in version of nice that has a + different interface from the one described in this + volume of IEEE Std 1003.1-2001. + + The term "utility" is used, rather than "command", to + highlight the fact that shell compound commands, pipe- + lines, and so on, cannot be used. Special built-ins also + cannot be used. However, "utility" includes user appli- + cation programs and shell scripts, not just utilities + defined in this volume of IEEE Std 1003.1-2001. + + Historical implementations of nice provide a nice value + range of 40 or 41 discrete steps, with the default nice + value being the midpoint of that range. By default, they + lower the nice value of the executed utility by 10. + + Some historical documentation states that the increment + value must be within a fixed range. This is misleading; + the valid increment values on any invocation are deter- + mined by the current process nice value, which is not + always the default. + + The definition of nice value is not intended to suggest + that all processes in a system have priorities that are + comparable. Scheduling policy extensions such as the + realtime priorities in the System Interfaces volume of + IEEE Std 1003.1-2001 make the notion of a single under- + lying priority for all scheduling policies problematic. + Some implementations may implement the nice-related fea- + tures to affect all processes on the system, others to + affect just the general time-sharing activities implied + by this volume of IEEE Std 1003.1-2001, and others may + have no effect at all.

The implementation shall also sup- + port the values 1, 2, 4, and 8, even if it pro- + vides no C-Language types of those sizes. The + implementation shall support the decimal value + corresponding to the C-language type long long. + The byte order used when interpreting numeric + values is implementation-defined, but shall cor- + respond to the order in which a constant of the + corresponding type is stored in memory on the + system. + + For the type specifier character f , the default + number of bytes shall correspond to the number of + bytes in the underlying implementation's basic + double precision floating-point data type.

Other non- + printable characters shall be written as one three-digit + octal number for each byte in the character. If the size + of a byte on the system is greater than nine bits, the + format used for non-printable characters is implementa- + tion-defined. Printable multi-byte characters shall be + written in the area corresponding to the first byte of + the character; the two-character sequence "**" shall be + written in the area corresponding to each remaining byte + in the character, as an indication that the character is + continued. When either the -j skip or -N count option is + specified along with the c type specifier, and this + results in an attempt to start or finish in the middle + of a multi-byte character, the result is implementation- + defined. + + The input data shall be manipulated in blocks, where a + block is defined as a multiple of the least common mul- + tiple of the number of bytes transformed by the speci- + fied output types. If the least common multiple is + greater than 16, the results are unspecified. Each + input block shall be written as transformed by each out- + put type, one per written line, in the order that the + output types were specified.

Those reasons are given + below along with rationale explaining why the standard + developers believe that this version does not suffer + from the indicated problem: + + The BSD and System V versions of od have + diverged, and the intersection of features pro- + vided by both does not meet the needs of the user + community. In fact, the System V version only + provides a mechanism for dumping octal bytes and + shorts, signed and unsigned decimal shorts, hexa- + decimal shorts, and ASCII characters. BSD added + the ability to dump floats, doubles, named ASCII + characters, and octal, signed decimal, unsigned + decimal, and hexadecimal longs. The version pre- + sented here provides more normalized forms for + dumping bytes, shorts, ints, and longs in octal, + signed decimal, unsigned decimal, and hexadeci- + mal; float, double, and long double; and named + ASCII as well as current locale characters. + + It would not be possible to come up with a + compatible superset of the BSD and System V flags + that met the requirements of the standard devel- + opers. The historical default od output is the + specified default output of this utility. None of + the option letters chosen for this version of od + conflict with any of the options to historical + versions of od. + + On systems with different sizes for short, int, + and long, there was no way to ask for dumps of + ints, even in the BSD version. Because of the way + options are named, the name space could not be + extended to solve these problems. This is why the + -t option was added (with type specifiers more + closely matched to the printf() formats used in + the rest of this volume of IEEE Std 1003.1-2001) + and the optional field sizes were added to the d + , f , o , u , and x type specifiers. It is also + one of the reasons why the historical practice + was not mandated as a required obsolescent form + of od. (Although the old versions of od are not + listed as an obsolescent form, implementations + are urged to continue to recognize the older + forms for several more years.) The a , c , f , o + , and x types match the meaning of the corre- + sponding format characters in the historical + implementations of od except for the default + sizes of the fields converted. The d format is + signed in this volume of IEEE Std 1003.1-2001 to + match the printf() notation. (Historical versions + of od used d as a synonym for u in this version. + The System V implementation uses s for signed + decimal; BSD uses i for signed decimal and s for + null-terminated strings.) Other than d and u , + all of the type specifiers match format charac- + ters in the historical BSD version of od. + + The sizes of the C-language types char, short, + int, long, float, double, and long double are + used even though it is recognized that there may + be zero or more than one compiler for the C lan- + guage on an implementation and that they may use + different sizes for some of these types. (For + example, one compiler might use 2 bytes shorts, 2 + bytes ints, and 4 bytes longs, while another com- + piler (or an option to the same compiler) uses 2 + bytes shorts, 4 bytes ints, and 4 bytes longs.) + Nonetheless, there has to be a basic size known + by the implementation for these types, corre- + sponding to the values reported by invocations of + the getconf utility when called with system_var + operands {UCHAR_MAX}, {USHORT_MAX}, {UINT_MAX}, + and {ULONG_MAX} for the types char, short, int, + and long, respectively. There are similar con- + stants required by the ISO C standard, but not + required by the System Interfaces volume of + IEEE Std 1003.1-2001 or this volume of + IEEE Std 1003.1-2001. They are {FLT_MANT_DIG}, + {DBL_MANT_DIG}, and {LDBL_MANT_DIG} for the types + float, double, and long double, respectively. If + the optional c99 utility is provided by the + implementation and used as specified by this vol- + ume of IEEE Std 1003.1-2001, these are the sizes + that would be provided. If an option is used that + specifies different sizes for these types, there + is no guarantee that the od utility is able to + interpret binary data output by such a program + correctly. + + This volume of IEEE Std 1003.1-2001 requires that + the numeric values of these lengths be recognized + by the od utility and that symbolic forms also be + recognized. Thus, a conforming application can + always look at an array of unsigned long data + elements using od -t uL. + + The method of specifying the format for the + address field based on specifying a starting off- + set in a file unnecessarily tied the two + together. The -A option now specifies the address + base and the -S option specifies a starting off- + set. + + It would be difficult to break the dependence on + U.S. ASCII to achieve an internationalized util- + ity. It does not seem to be any harder for od to + dump characters in the current locale than it is + for the ed or sed l commands. The c type speci- + fier does this without difficulty and is com- + pletely compatible with the historical implemen- + tations of the c format character when the cur- + rent locale uses a superset of the + ISO/IEC 646:1991 standard as a codeset. The a + type specifier (from the BSD a format character) + was left as a portable means to dump ASCII (or + more correctly ISO/IEC 646:1991 standard (IRV)) + so that headers produced by pax could be deci- + phered even on systems that do not use the + ISO/IEC 646:1991 standard as a subset of their + base codeset. + + The use of "**" as an indication of continuation of a + multi-byte character in c specifier output was chosen + based on seeing an implementation that uses this method. + The continuation bytes have to be marked in a way that + is not ambiguous with another single-byte or multi-byte + character. + + An early proposal used -S and -n, respectively, for the + -j and -N options eventually selected. These were + changed to avoid conflicts with historical implementa- + tions. + + The original standard specified -t o2 as the default + when no output type was given. This was changed to -t oS + (the length of a short) to accommodate a supercomputer + implementation that historically used 64 bits as its + default (and that defined shorts as 64 bits). This + change should not affect conforming applications. The + requirement to support lengths of 1, 2, and 4 was added + at the same time to address an historical implementation + that had no two-byte data types in its C compiler. + + The use of a basic integer data type is intended to + allow the implementation to choose a word size commonly + used by applications on that architecture. + +FUTURE DIRECTIONS + All option and operand interfaces marked as extensions + may be withdrawn in a future version. + +SEE ALSO + c99 , sed + +COPYRIGHT + Portions of this text are reprinted and reproduced in + electronic form from IEEE Std 1003.1, 2003 Edition, + Standard for Information Technology -- Portable Operat- + ing System Interface (POSIX), The Open Group Base Speci- + fications Issue 6, Copyright (C) 2001-2003 by the + Institute of Electrical and Electronics Engineers, Inc + and The Open Group.

(The reset vari- + able is used in this example to restore the initial + state.) + + Note the usage of: + + + rm "$path.out" > "$path.out" +
                    + + The pathchk command has already verified, at this point, + that $path.out is not truncated. + + With the noclobber option set, the shell verifies that + $path.out does not already exist before invoking rm. + + If the shell succeeded in creating $path.out, rm removes + it so that the application can create the file again in + the PROCESSING step. + + If the PROCESSING step wants the file to exist already + when it is invoked, the: + + + rm "$path.out" > "$path.out" + + should be replaced with: + + + > "$path.out" + + which verifies that the file did not already exist, but + leaves $path.out in place for use by PROCESSING. + +RATIONALE + The pathchk utility was new for the ISO POSIX-2:1993 + standard. It, along with the set -C( noclobber) option + added to the shell, replaces the mktemp, validfnam, and + create utilities that appeared in early proposals. All + of these utilities were attempts to solve several common + problems: + + Verify the validity (for several different defi- + nitions of "valid") of a pathname supplied by a + user, generated by an application, or imported + from an external source. + + Atomically create a file. + + Perform various string handling functions to gen- + erate a temporary filename. + + The create utility, included in an early proposal, pro- + vided checking and atomic creation in a single + invocation of the utility; these are orthogonal issues + and need not be grouped into a single utility. Note that + the noclobber option also provides a way of creating a + lock for process synchronization; since it provides an + atomic create, there is no race between a test for exis- + tence and the following creation if it did not exist. + + Having a function like tmpnam() in the ISO C standard is + important in many high-level languages. The shell pro- + gramming language, however, has built-in string manipu- + lation facilities, making it very easy to construct tem- + porary filenames. The names needed obviously depend on + the application, but are frequently of a form similar + to: + + + $TMPDIR/application_abbreviation$$.suffix + + In cases where there is likely to be contention for a + given suffix, a simple shell for or while loop can be + used with the shell noclobber option to create a file + without risk of collisions, as long as applications try- + ing to use the same filename name space are cooperating + on the use of files after they have been created. + +FUTURE DIRECTIONS + None. + +SEE ALSO + Redirection , set , test + +COPYRIGHT + Portions of this text are reprinted and reproduced in + electronic form from IEEE Std 1003.1, 2003 Edition, + Standard for Information Technology -- Portable Operat- + ing System Interface (POSIX), The Open Group Base Speci- + fications Issue 6, Copyright (C) 2001-2003 by the Insti- + tute of Electrical and Electronics Engineers, Inc and + The Open Group.

In + particular, the -s option does not allow the option let- + ter to be separated from its argument, and the options + -e, -i, and -n require that both arguments, if present, + not be separated from the option letter. + + The following options shall be supported. In the follow- + ing option descriptions, column, lines, offset, page, + and width are positive decimal integers; gap is a non- + negative decimal integer. + + +page Begin output at page number page of the formatted + input. + + -column + Produce multi-column output that is arranged in + column columns (the default shall be 1) and is + written down each column in the order in which + the text is received from the input file.

Because of its widespread use by + historical applications, the standard developers decided + to exempt this version of pr from many of the guide- + lines. + + Implementations are required to accept option-arguments + to the -h, -l, -o, and -w options whether presented as + part of the same argument or as a separate argument to + pr, as suggested by the Utility Syntax Guidelines. The + -n and -s options, however, are specified as in histori- + cal practice because they are frequently specified with- + out their optional arguments. If a were allowed + before the option-argument in these cases, a file oper- + and could mistakenly be interpreted as an option-argu- + ment in historical applications. + + The text about the minimum number of lines in multi-col- + umn output was included to ensure that a best effort is + made in balancing the length of the columns. There are + known historical implementations in which, for example, + 60-line files are listed by pr -2 as one column of 56 + lines and a second of 4. Although this is not a problem + when a full page with headers and trailers is produced, + it would be relatively useless when used with -t. + + Historical implementations of the pr utility have dif- + fered in the action taken for the -f option. BSD uses it + as described here for the -F option; System V uses it to + change trailing s on each page to a + and, if standard output is a TTY device, sends an + to standard error and reads a line from /dev/tty + before the first page. There were strong arguments from + both sides of this issue concerning historical practice + and as a result the -F option was added. XSI-conformant + systems support the System V historical actions for the + -f option. + + The field in the -l format is specified + only for the POSIX locale. As noted, the format can be + different in other locales.

If the preci- + sion is omitted, it shall be taken to be infinite, so + all bytes up to the end of the converted string shall be + written. + + For each conversion specification that consumes an argu- + ment, the next argument operand shall be evaluated and + converted to the appropriate type for the conversion as + specified below. + + The format operand shall be reused as often as necessary + to satisfy the argument operands. Any extra c or s con- + version specifiers shall be evaluated as if a null + string argument were supplied; other extra conversion + specifications shall be evaluated as if a zero argument + were supplied. If the format operand contains no con- + version specifications and argument operands are + present, the results are unspecified. + + If a character sequence in the format operand begins + with a '%' character, but does not form a valid conver- + sion specification, the behavior is unspecified. + + The argument operands shall be treated as strings if the + corresponding conversion specifier is b , c , or s ; + otherwise, it shall be evaluated as a C constant, as + described by the ISO C standard, with the following + extensions: + + A leading plus or minus sign shall be allowed. + + If the leading character is a single-quote or + double-quote, the value shall be the numeric + value in the underlying codeset of the character + following the single-quote or double-quote. + + If an argument operand cannot be completely converted + into an internal value appropriate to the corresponding + conversion specification, a diagnostic message shall be + written to standard error and the utility shall not exit + with a zero exit status, but shall continue processing + any remaining operands and shall write the value accumu- + lated at the time the error was detected to standard + output. + + It is not considered an error if an argument operand is + not completely used for a c or s conversion or if a + string operand's first or second character is used to + get the numeric value of a character. + +EXIT STATUS + The following exit values shall be returned: + + 0 Successful completion. + + >0 An error occurred. + + +CONSEQUENCES OF ERRORS + Default. + + The following sections are informative. + +APPLICATION USAGE + The floating-point formatting conversion specifications + of printf() are not required because all arithmetic in + the shell is integer arithmetic. The awk utility per- + forms floating-point calculations and provides its own + printf function. The bc utility can perform arbitrary- + precision floating-point arithmetic, but does not pro- + vide extensive formatting capabilities. (This printf + utility cannot really be used to format bc output; it + does not support arbitrary precision.) Implementations + are encouraged to support the floating-point conversions + as an extension. + + Note that this printf utility, like the printf() func- + tion defined in the System Interfaces volume of + IEEE Std 1003.1-2001 on which it is based, makes no spe- + cial provision for dealing with multi-byte characters + when using the %c conversion specification or when a + precision is specified in a %b or %s conversion specifi- + cation. Applications should be extremely cautious using + either of these features when there are multi-byte char- + acters in the character set. + + No provision is made in this volume of + IEEE Std 1003.1-2001 which allows field widths and pre- + cisions to be specified as '*' since the '*' can be + replaced directly in the format operand using shell + variable substitution. Implementations can also provide + this feature as an extension if they so choose. + + Hexadecimal character constants as defined in the ISO C + standard are not recognized in the format operand + because there is no consistent way to detect the end of + the constant. Octal character constants are limited to, + at most, three octal digits, but hexadecimal character + constants are only terminated by a non-hex-digit charac- + ter. In the ISO C standard, the "##" concatenation oper- + ator can be used to terminate a constant and follow it + with a hexadecimal character to be written. In the + shell, concatenation occurs before the printf utility + has a chance to parse the end of the hexadecimal con- + stant. + + The %b conversion specification is not part of the ISO C + standard; it has been added here as a portable way to + process backslash escapes expanded in string operands as + provided by the echo utility. See also the APPLICATION + USAGE section of echo for ways to use printf as a + replacement for all of the traditional versions of the + echo utility. + + If an argument cannot be parsed correctly for the corre- + sponding conversion specification, the printf utility is + required to report an error. Thus, overflow and extrane- + ous characters at the end of an argument being used for + a numeric conversion shall be reported as errors. + +EXAMPLES + To alert the user and then print and read a series of + prompts: + + + printf "\aPlease fill in the following: \nName: " + read name + printf "Phone number: " + read phone + + To read out a list of right and wrong answers from a + file, calculate the percentage correctly, and print them + out.

Only the general nature of the contents of prompts + are specified because implementations may desire more + descriptive prompts than those used on historical imple- + mentations. Therefore, an application not using the -f + option, or using the -i option, relies on the system to + provide the most suitable dialog directly with the user, + based on the behavior specified. + + The -r option is historical practice on all known sys- + tems. The synonym -R option is provided for consistency + with the other utilities in this volume of + IEEE Std 1003.1-2001 that provide options requesting + recursive descent through the file hierarchy. + + The behavior of the -f option in historical versions of + rm is inconsistent. In general, along with "forcing" the + unlink without prompting for permission, it always + causes diagnostic messages to be suppressed and the exit + status to be unmodified for nonexistent operands and + files that cannot be unlinked. In some versions, how- + ever, the -f option suppresses usage messages and system + errors as well. Suppressing such messages is not a ser- + vice to either shell scripts or users. + + It is less clear that error messages regarding files + that cannot be unlinked (removed) should be suppressed. + Although this is historical practice, this volume of + IEEE Std 1003.1-2001 does not permit the -f option to + suppress such messages. + + When given the -r and -i options, historical versions of + rm prompt the user twice for each directory, once before + removing its contents and once before actually attempt- + ing to delete the directory entry that names it. This + allows the user to "prune" the file hierarchy walk. His- + torical versions of rm were inconsistent in that some + did not do the former prompt for directories named on + the command line and others had obscure prompting behav- + ior when the -i option was specified and the permissions + of the file did not permit writing. The POSIX Shell and + Utilities rm differs little from historic practice, but + does require that prompts be consistent. Historical ver- + sions of rm were also inconsistent in that prompts were + done to both standard output and standard error. This + volume of IEEE Std 1003.1-2001 requires that prompts be + done to standard error, for consistency with cp and mv, + and to allow historical extensions to rm that provide an + option to list deleted files on standard output. + + The rm utility is required to descend to arbitrary + depths so that any file hierarchy may be deleted. This + means, for example, that the rm utility cannot run out + of file descriptors during its descent (that is, if the + number of file descriptors is limited, rm cannot be + implemented in the historical fashion where one file + descriptor is used per directory level). Also, rm is not + permitted to fail because of path length restrictions, + unless an operand specified by the user is longer than + {PATH_MAX}. + + The rm utility removes symbolic links themselves, not + the files they refer to, as a consequence of the depen- + dence on the unlink() functionality, per the DESCRIP- + TION.

When ordering options appear independent of + any key field specifications, the requested field order- + ing rules shall be applied globally to all sort keys. + When attached to a specific key (see -k), the specified + ordering options shall override all global ordering + options for that key. + + -d Specify that only s and alphanumeric char- + acters, according to the current setting of + LC_CTYPE , shall be significant in comparisons. + The behavior is undefined for a sort key to which + -i or -n also applies. + + -f Consider all lowercase characters that have + uppercase equivalents, according to the current + setting of LC_CTYPE , to be the uppercase equiva- + lent for the purposes of comparison. + + -i Ignore all characters that are non-printable, + according to the current setting of LC_CTYPE . + + -n Restrict the sort key to an initial numeric + string, consisting of optional s, optional + minus sign, and zero or more digits with an + optional radix character and thousands separators + (as defined in the current locale), which shall + be sorted by arithmetic value. An empty digit + string shall be treated as zero. Leading zeros + and signs on zeros shall not affect ordering. + + -r Reverse the sense of comparisons. + + + The treatment of field separators can be altered using + the options: + + -b Ignore leading s when determining the + starting and ending positions of a restricted + sort key. If the -b option is specified before + the first -k option, it shall be applied to all + -k options.

Each + occurrence of char shall be significant (for + example, delimits an empty field). + If -t is not specified, s shall be used as + default field separators; each maximal non-empty + sequence of s that follows a non- + shall be a field separator. + + + Sort keys can be specified using the options: + + -k keydef + The keydef argument is a restricted sort key + field definition. The format of this definition + is: + + + field_start[type][,field_end[type]] + + where field_start and field_end define a key field + restricted to a portion of the line (see the EXTENDED + DESCRIPTION section), and type is a modifier from the + list of characters 'b' , 'd' , 'f' , 'i' , 'n' , 'r' . + The 'b' modifier shall behave like the -b option, but + shall apply only to the field_start or field_end to + which it is attached. The other modifiers shall behave + like the corresponding options, but shall apply only to + the key field to which they are attached; they shall + have this effect if specified with field_start, + field_end, or both. If any modifier is attached to a + field_start or to a field_end, no option shall apply to + either. Implementations shall support at least nine + occurrences of the -k option, which shall be significant + in command line order. If no -k option is specified, a + default sort key of the entire line shall be used. + + When there are multiple key fields, later keys shall be + compared only after all earlier keys compare equal. + Except when the -u option is specified, lines that oth- + erwise compare equal shall be ordered as if none of the + options -d, -f, -i, -n, or -k were present (but with -r + still in effect, if it was specified) and with all bytes + in the lines significant to the comparison. The order in + which lines that still compare equal are written is + unspecified. + + +OPERANDS + The following operand shall be supported: + + file A pathname of a file to be sorted, merged, or + checked.

A warning message about correcting an incomplete + last line of an input file may be generated, but need + not affect the final exit status. + +OUTPUT FILES + If the -o option is in effect, the sorted input shall be + written to the file output. + +EXTENDED DESCRIPTION + The notation: + + + -k field_start[type][,field_end[type]] + + shall define a key field that begins at field_start and + ends at field_end inclusive, unless field_start falls + beyond the end of the line or after field_end, in which + case the key field is empty. A missing field_end shall + mean the last character of the line. + + A field comprises a maximal sequence of non-separating + characters and, in the absence of option -t, any preced- + ing field separator. + + The field_start portion of the keydef option-argument + shall have the form: + + + field_number[.first_character] + + Fields and characters within fields shall be numbered + starting with 1. The field_number and first_character + pieces, interpreted as positive decimal integers, shall + specify the first character to be used as part of a sort + key. If .first_character is omitted, it shall refer to + the first character of the field. + + The field_end portion of the keydef option-argument + shall have the form: + + + field_number[.last_character] + + The field_number shall be as described above for + field_start. The last_character piece, interpreted as a + non-negative decimal integer, shall specify the last + character to be used as part of the sort key. If + last_character evaluates to zero or .last_character is + omitted, it shall refer to the last character of the + field specified by field_number. + + If the -b option or b type modifier is in effect, char- + acters within a field shall be counted from the first + non- in the field. (This shall apply separately + to first_character and last_character.) + +EXIT STATUS + The following exit values shall be returned: + + 0 All input files were output successfully, or -c + was specified and the input file was correctly + sorted. + + 1 Under the -c option, the file was not ordered as + specified, or if the -c and -u options were both + specified, two input lines were found with equal + keys. + + >1 An error occurred. + + +CONSEQUENCES OF ERRORS + Default. + + The following sections are informative. + +APPLICATION USAGE + The default value for -t, , has different proper- + ties from, for example, -t "".

For example, this command + returns an exit status of zero, meaning the input was + already sorted: + + + sort -c -k 2 <b + xa + eof + + (assuming that a precedes the in the cur- + rent collating sequence). The field separator is not + included in a field when it is explicitly set via -t. + This is historical practice and allows usage such as: + + + sort -t "|" -k 2n < of the second + field as the sort key: + + + sort -k 2.2b,2.2b infile1 infile2 + + The following command prints the System V password file + (user database) sorted by the numeric user ID (the third + colon-separated field): + + + sort -t : -k 3,3n /etc/passwd + + The following command prints the lines of the already + sorted file infile, suppressing all but one occurrence + of lines having the same third field: + + + sort -um -k 3.1,3.0 infile + +RATIONALE + Examples in some historical documentation state that + options -um with one input file keep the first in each + set of lines with equal keys. This behavior was deemed + to be an implementation artifact and was not standard- + ized. + + The -z option was omitted; it is not standard practice + on most systems and is inconsistent with using sort to + sort several files individually and then merge them + together. The text concerning -z in historical documen- + tation appeared to require implementations to determine + the proper buffer length during the sort phase of opera- + tion, but not during the merge. + + The -y option was omitted because of non-portability. + The -M option, present in System V, was omitted because + of non-portability in international usage. + + An undocumented -T option exists in some implementa- + tions. It is used to specify a directory for intermedi- + ate files. Implementations are encouraged to support + the use of the TMPDIR environment variable instead of + adding an option to support this functionality. + + The -k option was added to satisfy two objections. + First, the zero-based counting used by sort is not con- + sistent with other utility conventions. Second, it did + not meet syntax guideline requirements. + + Historical documentation indicates that "setting -n + implies -b". The description of -n already states that + optional leading s are tolerated in doing the + comparison. If -b is enabled, rather than implied, by + -n, this has unusual side effects. When a character off- + set is used in a column of numbers (for example, to sort + modulo 100), that offset is measured relative to the + most significant digit, not to the column. Based upon a + recommendation from the author of the original sort + utility, the -b implication has been omitted from this + volume of IEEE Std 1003.1-2001, and an application wish- + ing to achieve the previously mentioned side effects has + to code the -b flag explicitly. + +FUTURE DIRECTIONS + None. + +SEE ALSO + comm , join , uniq , the System Interfaces volume of + IEEE Std 1003.1-2001, toupper() + +COPYRIGHT + Portions of this text are reprinted and reproduced in + electronic form from IEEE Std 1003.1, 2003 Edition, + Standard for Information Technology -- Portable Operat- + ing System Interface (POSIX), The Open Group Base Speci- + fications Issue 6, Copyright (C) 2001-2003 by the Insti- + tute of Electrical and Electronics Engineers, Inc and + The Open Group.

It has been modified to correspond to the ter- + minal driver termios. + + Output modes are specified only for XSI-conformant sys- + tems. All implementations are expected to provide stty + operands corresponding to all of the output modes they + support. + + The stty utility is primarily used to tailor the user + interface of the terminal, such as selecting the pre- + ferred ERASE and KILL characters. As an application pro- + gramming utility, stty can be used within shell scripts + to alter the terminal settings for the duration of the + script. + + The termios section states that individual disabling of + control characters is possible through the option + _POSIX_VDISABLE. If enabled, two conventions currently + exist for specifying this: System V uses "^-" , and BSD + uses undef. Both are accepted by stty in this volume of + IEEE Std 1003.1-2001. The other BSD convention of using + the letter 'u' was rejected because it conflicts with + the actual letter 'u' , which is an acceptable value for + a control character. + + Early proposals did not specify the mapping of "^c" to + control characters because the control characters were + not specified in the POSIX locale character set descrip- + tion file requirements. The control character set is + now specified in the Base Definitions volume of + IEEE Std 1003.1-2001, Chapter 3, Definitions so the his- + torical mapping is specified. Note that although the + mapping corresponds to control-character key assignments + on many terminals that use the ISO/IEC 646:1991 standard + (or ASCII) character encodings, the mapping specified + here is to the control characters, not their keyboard + encodings. + + Since termios supports separate speeds for input and + output, two new options were added to specify each dis- + tinctly. + + Some historical implementations use standard input to + get and set terminal characteristics; others use stan- + dard output. Since input from a login TTY is usually + restricted to the owner while output to a TTY is fre- + quently open to anyone, using standard input provides + fewer chances of accidentally (or maliciously) altering + the terminal settings of other users. Using standard + input also allows stty -a and stty -g output to be redi- + rected for later use. Therefore, usage of standard input + is required by this volume of IEEE Std 1003.1-2001. + +FUTURE DIRECTIONS + None. + +SEE ALSO + Shell Command Language , the Base Definitions volume of + IEEE Std 1003.1-2001, Chapter 11, General Terminal + Interface, + +COPYRIGHT + Portions of this text are reprinted and reproduced in + electronic form from IEEE Std 1003.1, 2003 Edition, + Standard for Information Technology -- Portable Operat- + ing System Interface (POSIX), The Open Group Base Speci- + fications Issue 6, Copyright (C) 2001-2003 by the Insti- + tute of Electrical and Electronics Engineers, Inc and + The Open Group.

Since this volume of + IEEE Std 1003.1-2001 does not specify the block size + used when doing input, tail need not read all of the + data from devices that only perform block transfers. + +EXAMPLES + The -f option can be used to monitor the growth of a + file that is being written by some other process. For + example, the command: + + + tail -f fred + + prints the last ten lines of the file fred, followed by + any lines that are appended to fred between the time + tail is initiated and killed. As another example, the + command: + + + tail -f -c 15 fred + + prints the last 15 bytes of the file fred, followed by + any bytes that are appended to fred between the time + tail is initiated and killed. + +RATIONALE + This version of tail was created to allow conformance to + the Utility Syntax Guidelines. The historical -b option + was omitted because of the general non-portability of + block-sized units of text. The -c option historically + meant "characters", but this volume of + IEEE Std 1003.1-2001 indicates that it means "bytes". + This was selected to allow reasonable implementations + when multi-byte characters are possible; it was not + named -b to avoid confusion with the historical -b. + + The origin of counting both lines and bytes is 1, match- + ing all widespread historical implementations. + + The restriction on the internal buffer is a compromise + between the historical System V implementation of 4096 + bytes and the BSD 32768 bytes. + + The -f option has been implemented as a loop that sleeps + for 1 second and copies any bytes that are available. + This is sufficient, but if more efficient methods of + determining when new data are available are developed, + implementations are encouraged to use them. + + Historical documentation indicates that tail ignores the + -f option if the input file is a pipe (pipe and FIFO on + systems that support FIFOs). On BSD-based systems, this + has been true; on System V-based systems, this was true + when input was taken from standard input, but it did not + ignore the -f flag if a FIFO was named as the file oper- + and. Since the -f option is not useful on pipes and all + historical implementations ignore -f if no file operand + is specified and standard input is a pipe, this volume + of IEEE Std 1003.1-2001 requires this behavior. However, + since the -f option is useful on a FIFO, this volume of + IEEE Std 1003.1-2001 also requires that if standard + input is a FIFO or a FIFO is named, the -f option shall + not be ignored. Although historical behavior does not + ignore the -f option for other file types, this is + unspecified so that implementations are allowed to + ignore the -f option if it is known that the file cannot + be extended. + + This was changed to the current form based on comments + noting that -c was almost never used without specifying + a number and that there was no need to specify -l if -n + number was given. + +FUTURE DIRECTIONS + None. + +SEE ALSO + head + +COPYRIGHT + Portions of this text are reprinted and reproduced in + electronic form from IEEE Std 1003.1, 2003 Edition, + Standard for Information Technology -- Portable Operat- + ing System Interface (POSIX), The Open Group Base Speci- + fications Issue 6, Copyright (C) 2001-2003 by the Insti- + tute of Electrical and Electronics Engineers, Inc and + The Open Group.

The parentheses can + be used to alter the normal precedence and asso- + ciativity. + + + The primaries with two elements of the form: + + + -primary_operator primary_operand + + are known as unary primaries.

Unless the application writer knows all the + cases that produce input to the script, invocations + like: + + + test "$1" -a "$2" + + should be written as: + + + test "$1" && test "$2" + + to avoid problems if a user supplied values such as $1 + set to '!' and $2 set to the null string. That is, in + cases where maximal portability is of concern, replace: + + + test expr1 -a expr2 + + with: + + + test expr1 && test expr2 + + and replace: + + + test expr1 -o expr2 + + with: + + + test expr1 || test expr2 + + but note that, in test, -a has higher precedence than -o + while "&&" and "||" have equal precedence in the shell. + + Parentheses or braces can be used in the shell command + language to effect grouping. + + Parentheses must be escaped when using sh; for example: + + + test \( expr1 -a expr2 \) -o expr3 + + This command is not always portable outside XSI-confor- + mant systems. The following form can be used instead: + + + ( test expr1 && test expr2 ) || test expr3 + + The two commands: + + + test "$1" + test ! "$1" + + could not be used reliably on some historical systems. + Unexpected results would occur if such a string expres- + sion were used and $1 expanded to '!' , '(' , or a known + unary primary. Better constructs are: + + + test -n "$1" + test -z "$1" + respectively. + + Historical systems have also been unreliable given the + common construct: + + + test "$response" = "expected string" + + One of the following is a more reliable form: + + + test "X$response" = "Xexpected string" + test "expected string" = "$response" + + Note that the second form assumes that expected string + could not be confused with any unary primary. If + expected string starts with '-' , '(' , '!' , or even + '=' , the first form should be used instead. Using the + preceding rules without the XSI marked extensions, any + of the three comparison forms is reliable, given any + input. (However, note that the strings are quoted in + all cases.) + + Because the string comparison binary primaries, '=' and + "!=" , have a higher precedence than any unary primary + in the greater than 4 argument case, unexpected results + can occur if arguments are not properly prepared.

Objections were + raised that the real problem is misuse of the test com- + mand ( [), and putting it into the shell is the wrong + way to fix the problem. Instead, proper documentation + and a new shell reserved word ( !) are sufficient. + + Tests that require multiple test operations can be done + at the shell level using individual invocations of the + test command and shell logicals, rather than using the + error-prone -o flag of test. + + XSI-conformant systems support more than four arguments. + + XSI-conformant systems support the combining of pri- + maries with the following constructs: + + expression1 -a expression2 + + True if both expression1 and expression2 are + true. + + expression1 -o expression2 + + True if at least one of expression1 and expres- + sion2 are true. + + ( expression ) + + True if expression is true. + + + In evaluating these more complex combined expressions, + the following precedence rules are used: + + The unary primaries have higher precedence than + the algebraic binary primaries. + + The unary primaries have lower precedence than + the string binary primaries. + + The unary and binary primaries have higher prece- + dence than the unary string primary. + + The ! operator has higher precedence than the -a + operator, and the -a operator has higher prece- + dence than the -o operator. + + The -a and -o operators are left associative. + + The parentheses can be used to alter the normal + precedence and associativity. + + The BSD and System V versions of -f are not the same. + The BSD definition was: + + -f file + True if file exists and is not a directory. + + + The SVID version (true if the file exists and is a regu- + lar file) was chosen for this volume of + IEEE Std 1003.1-2001 because its use is consistent with + the -b, -c, -d, and -p operands ( file exists and is a + specific file type). + + The -e primary, possessing similar functionality to that + provided by the C shell, was added because it provides + the only way for a shell script to find out if a file + exists without trying to open the file. Since implemen- + tations are allowed to add additional file types, a por- + table script cannot use: + + + test -b foo -o -c foo -o -d foo -o -f foo -o -p foo + + to find out if foo is an existing file. On historical + BSD systems, the existence of a file could be determined + by: + + + test -f foo -o -d foo + + but there was no easy way to determine that an existing + file was a regular file. An early proposal used the + KornShell -a primary (with the same meaning), but this + was changed to -e because there were concerns about the + high probability of humans confusing the -a primary with + the -a binary operator. + + The following options were not included in this volume + of IEEE Std 1003.1-2001, although they are provided by + some implementations. These operands should not be used + by new implementations for other purposes: + + -k file + True if file exists and its sticky bit is set. + + -C file + True if file is a contiguous file. + + -V file + True if file is a version file. + + + The following option was not included because it was + undocumented in most implementations, has been removed + from some implementations (including System V), and the + functionality is provided by the shell (see Parameter + Expansion . + + -l string + The length of the string string. + + + The -b, -c, -g, -p, -u, and -x operands are derived from + the SVID; historical BSD does not provide them. The -k + operand is derived from System V; historical BSD does + not provide it. + + On historical BSD systems, test -w directory always + returned false because test tried to open the directory + for writing, which always fails. + + Some additional primaries newly invented or from the + KornShell appeared in an early proposal as part of the + conditional command ( [[]]): s1 > s2, s1 < s2, str = + pattern, str != pattern, f1 -nt f2, f1 -ot f2, and f1 + -ef f2. They were not carried forward into the test + utility when the conditional command was removed from + the shell because they have not been included in the + test utility built into historical implementations of + the sh utility. + + The -t file_descriptor primary is shown with a mandatory + argument because the grammar is ambiguous if it can be + omitted.

It should be noted that implementations conform- + ing to the System Interfaces volume of + IEEE Std 1003.1-2001 do not take leap seconds into + account when computing seconds since the Epoch.

A portable + script can avoid this problem by using: + + + touch -- file + + or: + + + touch ./file + + in this case. + +EXAMPLES + None. + +RATIONALE + The functionality of touch is described almost entirely + through references to functions in the System Interfaces + volume of IEEE Std 1003.1-2001. In this way, there is no + duplication of effort required for describing such side + effects as the relationship of user IDs to the user + database, permissions, and so on. + + There are some significant differences between the touch + utility in this volume of IEEE Std 1003.1-2001 and those + in System V and BSD systems. They are upwards-compatible + for historical applications from both implementations: + + In System V, an ambiguity exists when a pathname that is + a decimal number leads the operands; it is treated as a + time value. In BSD, no time value is allowed; files may + only be touched to the current time. The -t time con- + struct solves these problems for future conforming + applications (note that the -t option is not historical + practice). + + The inclusion of the century digits, CC, is also new. + Note that a ten-digit time value is treated as if YY, + and not CC, were specified. The caveat about the range + of dates following the Epoch was included as recognition + that some implementations are not able to represent + dates beyond 18 January 2038 because they use signed int + as a time holder. + + The -r option was added because several comments + requested this capability. This option was named -f in + an early proposal, but was changed because the -f option + is used in the BSD version of touch with a different + meaning. + + At least one historical implementation of touch incre- + mented the exit code if -c was specified and the file + did not exist.

The sequence shall + cause the value whose encoding is represented by + the one, two, or three-digit octal integer to be + placed into the array. If the size of a byte on + the system is greater than nine bits, the valid + escape sequence used to represent a byte is + implementation-defined. Multi-byte characters + require multiple, concatenated escape sequences + of this type, including the leading '\' for each + byte. + + \character + The backslash-escape sequences in the Base Defi- + nitions volume of IEEE Std 1003.1-2001, Table + 5-1, Escape Sequences and Associated Actions ( + '\\' , '\a' , '\b' , '\f' , '\n' , '\r' , '\t' , + '\v' ) shall be supported. The results of using + any other character, other than an octal digit, + following the backslash are unspecified. + + c-c In the POSIX locale, this construct shall repre- + sent the range of collating elements between the + range endpoints (as long as neither endpoint is + an octal sequence of the form \octal), inclusive, + as defined by the collation sequence. The charac- + ters or collating elements in the range shall be + placed in the array in ascending collation + sequence. If the second endpoint precedes the + starting endpoint in the collation sequence, it + is unspecified whether the range of collating + elements is empty, or this construct is treated + as invalid. In locales other than the POSIX + locale, this construct has unspecified behavior. + + If either or both of the range endpoints are octal + sequences of the form \octal, this shall represent the + range of specific coded values between the two range + endpoints, inclusive. + + :class: + Represents all characters belonging to the + defined character class, as defined by the cur- + rent setting of the LC_CTYPE locale category.

A + BSD system pads string2 with the last character found in + string2. Thus, it is possible to do the following: + + + tr 0123456789 d + + which would translate all digits to the letter 'd' . + Since this area is specifically unspecified in this vol- + ume of IEEE Std 1003.1-2001, both the BSD and System V + behaviors are allowed, but a conforming application can- + not rely on the BSD behavior. It would have to code the + example in the following way: + + + tr 0123456789 '[d*]' + + It should be noted that, despite similarities in appear- + ance, the string operands used by tr are not regular + expressions. + + Unlike some historical implementations, this definition + of the tr utility correctly processes NUL characters in + its input stream. NUL characters can be stripped by + using: + + + tr -d '\000' + +EXAMPLES + The following example creates a list of all words in + file1 one per line in file2, where a word is taken to be + a maximal string of letters. + + + tr -cs "[:alpha:]" "[\n*]" file2 + + The next example translates all lowercase characters in + file1 to uppercase and writes the results to standard + output. + + + tr "[:lower:]" "[:upper:]" file2 + +RATIONALE + In some early proposals, an explicit option -n was added + to disable the historical behavior of stripping NUL + characters from the input. It was considered that auto- + matically stripping NUL characters from the input was + not correct functionality. However, the removal of -n + in a later proposal does not remove the requirement that + tr correctly process NUL characters in its input stream. + NUL characters can be stripped by using tr -d '\000'. + + Historical implementations of tr differ widely in syntax + and behavior. For example, the BSD version has not + needed the bracket characters for the repetition + sequence. The tr utility syntax is based more closely on + the System V and XPG3 model while attempting to accommo- + date historical BSD implementations. In the case of the + short string2 padding, the decision was to unspecify the + behavior and preserve System V and XPG3 scripts, which + might find difficulty with the BSD method. The assump- + tion was made that BSD users of tr have to make accommo- + dations to meet the syntax defined here. Since it is + possible to use the repetition sequence to duplicate the + desired behavior, whereas there is no simple way to + achieve the System V method, this was the correct, if + not desirable, approach. + + The use of octal values to specify control characters, + while having historical precedents, is not portable. The + introduction of escape sequences for control characters + should provide the necessary portability. It is recog- + nized that this may cause some historical scripts to + break. + + An early proposal included support for multi-character + collating elements. It was pointed out that, while tr + does employ some syntactical elements from REs, the aim + of tr is quite different; ranges, for example, do not + have a similar meaning (``any of the chars in the range + matches", versus "translate each character in the range + to the output counterpart"). As a result, the previously + included support for multi-character collating elements + has been removed. What remains are ranges in current + collation order (to support, for example, accented char- + acters), character classes, and equivalence classes. + + In XPG3 the [: class:] and [= equiv=] conventions are + shown with double brackets, as in RE syntax. However, tr + does not implement RE principles; it just borrows part + of the syntax. Consequently, [: class:] and [= equiv=] + should be regarded as syntactical elements on a par with + [ x* n], which is not an RE bracket expression. + + The standard developers will consider changes to tr that + allow it to translate characters between different char- + acter encodings, or they will consider providing a new + utility to accomplish this. + + On historical System V systems, a range expression + requires enclosing square-brackets, such as: + + + tr '[a-z]' '[A-Z]' + + However, BSD-based systems did not require the brackets, + and this convention is used here to avoid breaking large + numbers of BSD scripts: + + + tr a-z A-Z + + The preceding System V script will continue to work + because the brackets, treated as regular characters, are + translated to themselves. However, any System V script + that relied on "a-z" representing the three characters + 'a' , '-' , and 'z' have to be rewritten as "az-" . + + The ISO POSIX-2:1993 standard had a -c option that + behaved similarly to the -C option, but did not supply + functionality equivalent to the -c option specified in + IEEE Std 1003.1-2001. This meant that historical prac- + tice of being able to specify tr -d\200-\377 (which + would delete all bytes with the top bit set) would have + no effect because, in the C locale, bytes with the val- + ues octal 200 to octal 377 are not characters. + + The earlier version also said that octal sequences + referred to collating elements and could be placed adja- + cent to each other to specify multi-byte characters. + However, it was noted that this caused ambiguities + because tr would not be able to tell whether adjacent + octal sequences were intending to specify multi-byte + characters or multiple single byte characters. + IEEE Std 1003.1-2001 specifies that octal sequences + always refer to single byte binary values. + +FUTURE DIRECTIONS + None. + +SEE ALSO + sed + +COPYRIGHT + Portions of this text are reprinted and reproduced in + electronic form from IEEE Std 1003.1, 2003 Edition, + Standard for Information Technology -- Portable Operat- + ing System Interface (POSIX), The Open Group Base Speci- + fications Issue 6, Copyright (C) 2001-2003 by the Insti- + tute of Electrical and Electronics Engineers, Inc and + The Open Group.

These tests verify the meaning of adja- + cent. The uniq utility views the input data as a + sequence of strings delimited by '\n' . Accordingly, for + the fieldsth member of the sequence, uniq interprets + unique or repeated adjacent lines strictly relative to + the fields+1th member. + + This first example tests the line counting option, com- + paring each line of the input file data starting from + the second field: + + + uniq -c -f 1 uniq_0I.t + 1 #01 foo0 bar0 foo1 bar1 + 1 #02 bar0 foo1 bar1 foo0 + 1 #03 foo0 bar0 foo1 bar1 + 1 #04 + 2 #05 foo0 bar0 foo1 bar1 + 1 #07 bar0 foo1 bar1 foo0 + + The number '2' , prefixing the fifth line of output, + signifies that the uniq utility detected a pair of + repeated lines. Given the input data, this can only be + true when uniq is run using the -f 1 option (which shall + cause uniq to ignore the first field on each input + line). + + The second example tests the option to suppress unique + lines, comparing each line of the input file data start- + ing from the second field: + + + uniq -d -f 1 uniq_0I.t + #05 foo0 bar0 foo1 bar1 + + This test suppresses repeated lines, comparing each line + of the input file data starting from the second field: + + + uniq -u -f 1 uniq_0I.t + #01 foo0 bar0 foo1 bar1 + #02 bar0 foo1 bar1 foo1 + #03 foo0 bar0 foo1 bar1 + #04 + #07 bar0 foo1 bar1 foo0 + + This suppresses unique lines, comparing each line of the + input file data starting from the third character: + + + uniq -d -s 2 uniq_0I.t + + In the last example, the uniq utility found no input + matching the above criteria. + +RATIONALE + Some historical implementations have limited lines to be + 1080 bytes in length, which does not meet the implied + {LINE_MAX} limit. + +FUTURE DIRECTIONS + None. + +SEE ALSO + comm , sort + +COPYRIGHT + Portions of this text are reprinted and reproduced in + electronic form from IEEE Std 1003.1, 2003 Edition, + Standard for Information Technology -- Portable Operat- + ing System Interface (POSIX), The Open Group Base Speci- + fications Issue 6, Copyright (C) 2001-2003 by the Insti- + tute of Electrical and Electronics Engineers, Inc and + The Open Group.

Due to international requirements, the -m option + (reminiscent of "multi-byte") was added to obtain actual + character counts. + + Early proposals only specified the results when input + files were text files.
