Here you mount /mnt/jazz and store the standard output from mount in the variable $mount_jazz. > $unmount_jazz = `umount /mnt/jazz`; The next thing you do is unmount /mnt/jazz and store the standard output from umount in the variable $unmount_jazz. Perhaps you should run this at the _end_ of your program. > $backup_spool = `tar -cf /mnt/jazz/backup_spool.tar /var/spool/`; > $backup_rootmail = `tar -cf /mnt/jazz/backup_rootmail.tar /root/mail`; > $backup_adamchrmail = `tar -cf /mnt/jazz/backup_adamchrmail.tar /home/adamchr > $backup_etc = `tar -cf /mnt/jazz/backup_etc.tar /etc`; > $bzip_jazz = `bzip2 -kf /mnt/jazz/*.tar`; > $erase_tar = `rm -f /mnt/jazz/*.tar`; > > #$mount_jazz; > $backup_spool; > $backup_rootmail; > $backup_adamchrmail; > $backup_etc; > $erase_tar; John -- use Perl; program fulfillment -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
