in reply to wait for the system command to complete process

G'day kulls,

I'm not an nmon user and I don't have it installed so I can't test any of the following.

My understanding is that nmon starts a daemon so the command will return before the daemon finishes. That would be why you're only getting part of the output.

You don't show any use of $result: I suspect system would be a better choice than backticks.

If you are only running it for a few seconds (-s3 -c1), then sleep may be a viable option; however, I'd probably lean more towards tailing file.out - File::Tail may be helpful for that.
