I'm starting to think about how to keep my backup files with names that let me know when I did them and allow wildcard manipulation in the future. I decided that I would use a period, 4 character year and 3 character day of year. For example, the "owtools" file I backed up has the name "owtools.2008343" (this is the 343 day of 2008). The command to do this is:
cp -i owtools `date '+owtools.%Y%j'`
If anyone can come up with a way to wildcard this (owtools*) so I could do them all at once, that would be great.
Thanks..
