Re: [monitoring-like] would like to be warned when I have mail (fetchmail -c)

[Gerhard Siegesmund]

Hello

I did something similar, but asking an imap-Server for the number of
mails with fetchmail -c. Problem was: The query took several seconds to
succeed, in which time my screen freezed as the hardstatusline was
waiting for the info.

I read the manpage and found "backtick 1 0 0 script" which is supposed
to start the script and just wait for new messages to stdout to output
them on the hardstatusline. Works great! Except for one thing: The
script doesn't get killed, if the screen is ended. This means I have to
stop the mailcheck-scripts which are created from screen by hand.

Is there anything I can do to automatically stop the started scripts if
the parent-screen is terminated?
