TSORT(1) DOMAIN/IX Reference Manual (SYS5) TSORT(1)
NAME
tsort - topological sort
USAGE
tsort [ file ]
DESCRIPTION
Tsort 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.
CAUTIONS
Tsort uses a quadratic algorithm. This is not worth fixing
for the typical use of ordering a library archive file.
DIAGNOSTICS
Odd data: there is an odd number of fields in the input
file.
