I think that you're on the right track but you don't put the tar in the background. If you do that then you will need a second process watching for the first to complete. What you really want to do is put a little shell script around the tar job, have it do the mailing, and background that.

Perl is good for this, but not actually necessary. Pass in the relevant tape parameters and addresses; have good defaults. Separate the error output and use that as the body of your mail message. Watch the errorlevel returned by the tar command; if it isn't zero, you want to fire off an alert message -- different subject? different recipients? Now you say tapejob -o tape94a -f 101201_80W2Y_236F.tgz -m sgold...@mit.edu & And it all works nicely. If you're going to fire these off by hand, 'screen' is an excellent tool to have around. If not, 'cron' or 'at' might be your friends. -dsr- -- http://tao.merseine.nu/~dsr/eula.html is hereby incorporated by reference.
