how to use date command in filenaming for cron job?

[angst]

Hello,
I'm not an advanced linux user though I've been using for years, here's my question.

I'm trying to setup a cron job to backup my websites daily, normally when I manually do this I include the date in the name of the created file, like: website-12-10-09.tar.gz

now I'm wondering if there is a way to dynamically include the date, something like:


tar -zcvf websites[date '+-%d-%m-%y'].tar.gz websites/


any ideas would be great!
cheers,
-Ken

You're real close. It would be:

tar -zcvf websites`date '+-%d-%m-%y'`.tar.gz websites/

hehe,, yes I knew it was something simple but wasn't sure of the syntax. but that did the trick!

much appreciated!
