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".

There are two forms: $(command) or `command` So your command goes: tar -czf /mnt/archive/autoarchive/`date` myfiles greetings, Johannes -- "More than machinery we need humanity" -- Charlie Chaplin, The Great Dictator -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Basically, tar czf myFiles.`date`.tar.gz myfiles though that gets you whitespaces in the file name. You should use date(1) with a format string, have a look in date's manpage.

How do I do this in bash ??
Hi all ... I am writting a weekly automated backup script, very simple .. tars a directory called 'myfiles' to a second hard drive. Works AOK except I want the name of the file written by tar to be the time and date. So I get a list of tared dated backups I know 'date' gives me exactly what I want but I cant figure out how to get tar to write a file with the value of date as its file name ... #! /bin/sh # Backup entire 'myfiles/' directory, name it with the date. cd /usr/local/ tar -czf /mnt/archive/autoarchive/date myfiles I put this in /etc/cron.weekly and I get a file called date !!??? I have tried '' and "" all to no avail Any hints ?? Dave -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
