What you want is backticks (`date`). Since date's default output isn't very good as a filename you probably want to specify the output format. I would use something like this: tar czf /mnt/archive/autoarchive/`date '+%Y%m%d'`.tar.gz myfiles which would give you a file named 20030119.tar.gz. The reason I use year-month-day format is that the alphabetical sorting that ls does by default will match the chronological order of the files. -- Michael Heironimus -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
