Re: not getting any result...

The error results of useradd appear to go to STDERR instead of STDOUT. You can redirect them to STDOUT, and therefore capture the results, like this: my $username='username'; my $rescmd=`/usr/sbin/useradd -s /bin/false $username 2>&1`; chomp $rescmd; print "Result is $rescmd\n"; On Fri, 2003-01-3
