Several solutions
If you care about the program's output, use backticks, like so:
my $result = `ls /home`;
print $result;
Otherwise, you can use
system:
system('cp /tmp/foo /tmp/bar') || die "Can't run command";
(although you should NEVER use
cp when you can roll your
own in perl)
Also, go see the thread on Running External Commands that has
another method (pipe opens), plus valuable info on taint checking.
