The second and succeeding copies of + repeated adjacent input lines shall not be written. + + Repeated lines in the input shall not be detected if + they are not adjacent. + +OPTIONS + The uniq 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: + + -c Precede each output line with a count of the num- + ber of times the line occurred in the input. + + -d Suppress the writing of lines that are not + repeated in the input. + + -f fields + Ignore the first fields fields on each input line + when doing comparisons, where fields is a posi- + tive decimal integer. A field is the maximal + string matched by the basic regular expression: + + + [[:blank:]]*[^[:blank:]]* + + If the fields option-argument specifies more fields than + appear on an input line, a null string shall be used for + comparison. + + -s chars + Ignore the first chars characters when doing com- + parisons, where chars shall be a positive decimal + integer. If specified in conjunction with the -f + option, the first chars characters after the + first fields fields shall be ignored. If the + chars option-argument specifies more characters + than remain on an input line, a null string shall + be used for comparison. + + -u Suppress the writing of lines that are repeated + in the input. + + +OPERANDS + The following operands shall be supported: + + input_file + A pathname of the input file. If the input_file + operand is not specified, or if the input_file is + '-' , the standard input shall be used. + + output_file + A pathname of the output file. If the output_file + operand is not specified, the standard output + shall be used. The results are unspecified if the + file named by output_file is the file named by + input_file. + + +STDIN + The standard input shall be used only if no input_file + operand is specified or if input_file is '-' . See the + INPUT FILES section. + +INPUT FILES + The input file shall be a text file. + +ENVIRONMENT VARIABLES + The following environment variables shall affect the + execution of uniq: + + LANG Provide a default value for the internationaliza- + tion variables that are unset or null. (See the + Base Definitions volume of IEEE Std 1003.1-2001, + Section 8.2, Internationalization Variables for + the precedence of internationalization variables + used to determine the values of locale cate- + gories.) + + LC_ALL If set to a non-empty string value, override the + values of all the other internationalization + variables. + + LC_COLLATE + + Determine the locale for ordering rules. + + LC_CTYPE + Determine the locale for the interpretation of + sequences of bytes of text data as characters + (for example, single-byte as opposed to multi- + byte characters in arguments and input files) and + which characters constitute a in the cur- + rent locale. + + LC_MESSAGES + Determine the locale that should be used to + affect the format and contents of diagnostic mes- + sages written to standard error. + + NLSPATH + Determine the location of message catalogs for + the processing of LC_MESSAGES . + + +ASYNCHRONOUS EVENTS + Default. + +STDOUT + The standard output shall be used only if no output_file + operand is specified. See the OUTPUT FILES section. + +STDERR + The standard error shall be used only for diagnostic + messages. + +OUTPUT FILES + If the -c option is specified, the output file shall be + empty or each line shall be of the form: + + + "%d %s", , + + otherwise, the output file shall be empty or each line + shall be of the form: + + + "%s", + +EXTENDED DESCRIPTION + None. + +EXIT STATUS + The following exit values shall be returned: + + 0 The utility executed successfully. + + >0 An error occurred. + + +CONSEQUENCES OF ERRORS + Default. + + The following sections are informative. + +APPLICATION USAGE + The sort utility can be used to cause repeated lines to + be adjacent in the input file. + +EXAMPLES + The following input file data (but flushed left) was + used for a test series on uniq: + + + #01 foo0 bar0 foo1 bar1 + #02 bar0 foo1 bar1 foo1 + #03 foo0 bar0 foo1 bar1 + #04 + #05 foo0 bar0 foo1 bar1 + #06 foo0 bar0 foo1 bar1 + #07 bar0 foo1 bar1 foo0 + + What follows is a series of test invocations of the uniq + utility that use a mixture of uniq options against the + input file data. 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.
