Hello,
I have a question:
is there a way to have a "for" cycle done a certain number of times. For example in c++ I can do this:
for (i=o;i<10;i++)
and the cycle will be repeated 10 times.
in UNIX for example I do this:

and the cycle will be repeated... (6 Replies)

TSORT(1) BSD General Commands Manual TSORT(1)
NAME
tsort -- topological sort of a directed graph
SYNOPSIS
tsort [-dlq] [file]
DESCRIPTION
The tsort utility takes a list of pairs of node names representing directed arcs in a graph and prints the nodes in topological order on
standard output. Input is taken from the named file, or from standard input if no file is given.
There must be an even number of nodes in the input. Node names specified on the same line should be white space separated.
Presence of a node in a graph can be represented by an arc from the node to itself. This is useful when a node is not connected to any other
nodes.
If the graph contains a cycle (and therefore cannot be properly sorted), one of the arcs in the cycle is ignored and the sort continues.
Cycles are reported on standard error.
The options are as follows:
-d Turn on debugging.
-l Search for and display the longest cycle. Can take a very long time.
-q Do not display informational messages about cycles. This is primarily intended for building libraries, where optimal ordering is not
critical, and cycles occur often.

HISTORY
The tsort command appeared in Version 7 AT&T UNIX. This tsort command and manual page are derived from sources contributed to Berkeley by
Michael Rendell of Memorial University of Newfoundland.
BUGS
The tsort utility does not recognize multibyte characters.
