tsort(1)          (Software Generation System Utilities)           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.
