Pairs of different items indicate ordering. + Pairs of identical items indicate presence, but not + ordering. + +OPTIONS + None. + +OPERANDS + The following operand shall be supported: + + file A pathname of a text file to order. If no file + operand is given, the standard input shall be + used. + + +STDIN + The standard input shall be a text file that is used if + no file operand is given. + +INPUT FILES + The input file named by the file operand is a text file. + +ENVIRONMENT VARIABLES + The following environment variables shall affect the + execution of tsort: + + 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). + + 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 a text file consisting of + the order list produced from the partially ordered + input. + +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 + The LC_COLLATE variable need not affect the actions of + tsort. The output ordering is not lexicographic, but + depends on the pairs of items given as input. + +EXAMPLES + The command: + + + tsort <<EOF + a b c c d e + g g + f g e f + h h + EOF + + produces the output: + + + a + b + c + d + e + f + g + h + +RATIONALE + None. + +FUTURE DIRECTIONS + None. + +SEE ALSO + None. + +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.
