in reply to breaking from a script

To exit from the script you can use  exit $errorcode;
I would use a reg ex to match that string i guess. Or check the error level of the adduser command (which is probably a better option for what your trying to do). Do this using perls built in system call.If you try to add a user that already exists it probably wont exit with 0.
if (!system("adduser bob")) { exit 0; } else { exit 122 }

    hi again, excuse me for my complete stupidity, but how can i integrate that into my script? where would i print the error message in this code?
      if (!system("adduser bob")) { print "system returned 0 everything is ok"; exit 0; } else { print "there was an error, exit and return 127 to the os"; exit 122; }
