By default, tabstops shall be set at + every eighth column position. Each shall be + copied to the output, and shall cause the column posi- + tion count for tab calculations to be decremented; the + count shall never be decremented to a value less than + one. + +OPTIONS + The unexpand utility shall conform to the Base Defini- + tions volume of IEEE Std 1003.1-2001, Section 12.2, + Utility Syntax Guidelines. + + The following options shall be supported: + + -a In addition to translating s at the begin- + ning of each line, translate all sequences of two + or more s immediately preceding a tab stop + to the maximum number of s followed by the + minimum number of s needed to fill the + same column positions originally filled by the + translated s. + + -t tablist + Specify the tab stops. The application shall + ensure that the tablist option-argument is a sin- + gle argument consisting of a single positive dec- + imal integer or multiple positive decimal inte- + gers, separated by s or commas, in ascend- + ing order. If a single number is given, tabs + shall be set tablist column positions apart + instead of the default 8. If multiple numbers are + given, the tabs shall be set at those specific + column positions. + + The application shall ensure that each tab-stop position + N is an integer value greater than zero, and the list + shall be in strictly ascending order. This is taken to + mean that, from the start of a line of output, tabbing + to position N shall cause the next character output to + be in the ( N+1)th column position on that line. When + the -t option is not specified, the default shall be the + equivalent of specifying -t 8 (except for the interac- + tion with -a, described below). + + No -to- conversions shall occur for charac- + ters at positions beyond the last of those specified in + a multiple tab-stop list. + + When -t is specified, the presence or absence of the -a + option shall be ignored; conversion shall not be limited + to the processing of leading s. + + +OPERANDS + The following operand shall be supported: + + file A pathname of a text file to be used as input. + + +STDIN + See the INPUT FILES section. + +INPUT FILES + The input files shall be text files. + +ENVIRONMENT VARIABLES + The following environment variables shall affect the + execution of unexpand: + + 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_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), + the processing of s and s, and for + the determination of the width in column posi- + tions each character would occupy on an output + device. + + 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 equivalent to the input + files with the specified -to- conversions. + +STDERR + The standard error shall be used only for diagnostic + messages. + +OUTPUT FILES + None. + +EXTENDED DESCRIPTION + None. + +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 + One non-intuitive aspect of unexpand is its restriction + to leading spaces when neither -a nor -t is specified. + Users who always want to convert all spaces in a file + can easily alias unexpand to use the -a or -t 8 option. + +EXAMPLES + None. + +RATIONALE + On several occasions, consideration was given to adding + a -t option to the unexpand utility to complement the -t + in expand (see expand ). The historical intent of unex- + pand was to translate multiple s into tab stops, + where tab stops were a multiple of eight column posi- + tions on most UNIX systems. An early proposal omitted -t + because it seemed outside the scope of the User Porta- + bility Utilities option; it was not described in any of + the base documents. However, hard-coding tab stops + every eight columns was not suitable for the interna- + tional community and broke historical precedents for + some vendors in the FORTRAN community, so -t was + restored in conjunction with the list of valid extension + categories considered by the standard developers. Thus, + unexpand is now the logical converse of expand. + +FUTURE DIRECTIONS + None. + +SEE ALSO + expand , tabs + +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.
