Scripts have two "channels" for messages, one for output and one for error messages. After your command, `perlOutput` contains messages from the former. If you append `2>&1` to the command (inside the backticks) it will contain messages from either. If a script doesn't use the error channel it won't make any difference.
Glad I asked. Does make a difference. The script does return error info. I had taken it out thinking to not have stuff in the script that might cause problems and took it out before noticing the difference.
