Re: Help with Cron pleazzzzzzzzzzzz
In response to VeeJay [EMAIL PROTECTED]: Hello Gurus…. I am running a status script written in Perl (*status.pl*) and want to have it *Always Running*. How can I check through CRON that status.pl is running and if NO, then start the script execution again? Please help and advise… Have you considered something like daemontools? It's designed for such a task, as opposed to reinventing the wheel. -- Bill Moran http://www.potentialtech.com ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

You could write a shell script something like: #!/bin/bash ps -ax | grep 'status.pl' if [ $q -eq 0 ] then status.pl fi grep will return zero if it finds a line containing 'status.pl', and 1 otherwise. in crontab, use * * * * * /full/path/to/script-above and it will check every minute. But a better fix would be to find the bug in status.pl that makes it crash! -- Mike Jeays http://www.jeays.ca ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

You could write a shell script something like: A couple nits: #!/bin/bash #!/bin/sh ps -ax | grep 'status.pl' This should probably be something like ps -ax | grep 'status.pl' | grep -v grep so you don't get false positives from the grep process itself.
