TSORT(1)                    General Commands Manual                   TSORT(1)



NAME
       tsort - topological sort

SYNOPSIS
       tsort [ filename ]

DESCRIPTION
       tsort  produces  on the standard output a totally ordered list of items
       consistent with a partial ordering of  items  mentioned  in  the  input
       filename.   If  no  filename is specified, the standard input is under-
       stood.

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

SEE ALSO
       lorder(1)

BUGS
       Uses a quadratic algorithm; not worth fixing for  the  typical  use  of
       ordering a library archive file.
