rename file based on file's timestamp

Hi,

Hopefully, a simple request...

I have a series of files in a directory:

-rw-r--r--  1 ozzmosis  ozzmosis  115201253 Jul 28  2006
209.mp3
-rw-r--r--  1 ozzmosis  ozzmosis  115201253 Jul 31  2006
212.mp3
-rw-r--r--  1 ozzmosis  ozzmosis  115201253 Aug  1  2006
213.mp3
-rw-r--r--  1 ozzmosis  ozzmosis  115201253 Aug  2  2006
214.mp3
-rw-r--r--  1 ozzmosis  ozzmosis  115201253 Aug  3  2006
215.mp3

etc.

Now I want to rename these so the new filenames are based on
the file's
timestamp, like so:

-rw-r--r--  1 ozzmosis  ozzmosis  115201253 Jul 28  2006
2006-07-28.mp3
-rw-r--r--  1 ozzmosis  ozzmosis  115201253 Jul 31  2006
2006-07-31.mp3
-rw-r--r--  1 ozzmosis  ozzmosis  115201253 Aug  1  2006
2006-08-01.mp3
-rw-r--r--  1 ozzmosis  ozzmosis  115201253 Aug  2  2006
2006-08-02.mp3
-rw-r--r--  1 ozzmosis  ozzmosis  115201253 Aug  3  2006
2006-08-03.mp3

I can write some Python code to do this, but maybe there is
another way,
perhaps using a shell script.  Any thoughts?

Thanks,

Regards
Andrew

Simple bash script to do this (untested):

for i in $*
do
	mv $i `stat -f %Sm -t %Y-%m-%d`.mp3
done

HTH!

just pay attention at the situation when two files have the
same timestamp..

A script is a script whether it is in Python, Perl or one of
the common
shells.   Use what works for you.  I'd use Perl, but I am
already
somewhat familiar with Perl.
