Based on your post, I think the reason you are receiving two e-mails is -- In your backup script, you are redirecting stdout to the file bakupweekly.log, but you are NOT redirecting stderr to the same file. So stderr is being sent to root@mail because its part of the cronjob output, but stdout is being redirected to your backup file and then mailed to another account. In other words, your tar syntax is causing tar to output to both stdout and stderr. To fix, choose one of the following options: 1) fix your tar syntax so that it does not generate stderr output. 2) Add the MAILTO variable to your backup script and then remove all redirects along with your 'mail' command. It's no longer needed. Ex: #!/bin/sh MAILTO=admin@mail echo Backup started at `date` etc... etc... 3) Change each line in your shell script that redirects output to include stderr... EX: echo Backup started at `date` >bakupweekly.log 2>&1 Steve Cowles -- redhat-list mailing list unsubscribe mailto:redhat-list-request@;redhat.com?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/redhat-list
