tsort(1)               UNIX System V(C Development Set)                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.
