Tar, gzip and date in file name
===============================

I often save directories in *.tar.gz files. For some purposes I add the
current date to the file name:

	tar czvf mydir-`date +%Y-%m-%d` mydir

It's  easy but  I  always have  to type  the  whole command.  Moreover,
directory name have to be typed twice. I have been doing this for years
and on all my *nix machines.

For some reasons, only today I found this to be too annoying. So I have
wrote a short bash script (it might  work elsewhere but at the moment I
only tried it with the bash) [1],[2].
