`tsort': Topological sort ========================= `tsort' performs a topological sort on the given FILE, or standard input if no input file is given or for a FILE of `-'. Synopsis: tsort [OPTION] [FILE] `tsort' reads its input as pairs of strings, separated by blanks, indicating a partial ordering. The output is a total ordering that corresponds to the given partial ordering. For example tsort <<EOF a b c d e f b c d e EOF will produce the output a b c d e f `tsort' will detect cycles in the input and writes the first cycle encountered to standard error. Note that for a given partial ordering, generally there is no unique total ordering. The only options are `--help' and `--version'. Note: Common options.
