in thread Net::Telnet: remote job completion

Assuming I go with the waitfor() option, do I still have to pass $telnet->cmd("\cC") to force Ctrl-C on my tail command after each job? Have no way of testing it right now but I would assume so if I'm to get the prompt again.

    Yes.  In order to try, I installed telnetd in a sandbox, and it seems to work fine (i.e. ->cmd("\cC") actually does get a SIGINT being delivered to the tail -f).

    ... $telnet->print("/path/to/script") or die $telnet->errmsg; $telnet->print("tail -f /tmp/testxxx") or die $telnet->errmsg; $telnet->waitfor('/FINISHED/'); $telnet->cmd("\cC") or die $telnet->errmsg; ... (run next script)

    where script goes in the background and writes a few lines to /tmp/testxxx, with the last line being "FINISHED".

      Thanks! I'll go with this solution. The only problem I found is my timeout in waitfor() as the jobs can run for quite a while. I'll have to adjust for that.
