TSORT(1)             INTERACTIVE UNIX System             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 ord-
               ering.  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.
