TSORT(1)                                                 TSORT(1)



     NAME
          tsort - topological sort

     SYNOPSIS
          tsort [file]

     DESCRIPTION
          The tsort command produces on the standard output a totally
          ordered list of items consistent with a partial ordering of
          items mentioned in the input file.  If no file is specified,
          the standard input is understood.

          The input consists of pairs of items (nonempty strings)
          separated by blanks.  Pairs of different items indicate
          ordering.  Pairs of identical items indicate presence, but
          not ordering.

     SEE ALSO
          lorder(1).

     DIAGNOSTICS
          Odd data: there is an odd number of fields in the input
          file.
