As already mentioned, you probably want to use the system command. I would add that you should also use the form:

my $rc = system "some command";
if ($rc != $whatever_return_code_you_expect) {
   # do some debugging stuff
}

to take advantage of whatever error codes/messages that may be returned.

If the code and the comments disagree, then both are probably wrong. -- Norm Schryer
