Rename file to same name plus datestamp of last modification.

mv -iv $FILENAME{,.$(stat -c %y $FILENAME | awk '{print $1}')}
Note that the -i will not help in a script. Proper error checking is required.
Sample Output
$ touch -d "yesterday" /tmp/testfile
$ FILENAME=/tmp/testfile
$ mv -iv $FILENAME{,.$(stat -c %y $FILENAME | awk '{print $1}')}
`/tmp/testfile' -> `/tmp/testfile.2014-11-30'

What Others Think

What a nice twist on the old backup-my-file routine. However, I can save a few characters and get rid of the dependency on awk F2=$(stat -c %y $FILENAME); mv -iv $FILENAME{,.${F2%% *}} Get the timestamp in F2, then use bash substitution to shorten it. Unfortunately, I can't just put the stat clause in the mv command :-(

A slightly tidier variant: mv -iv "$FILENAME"{,.$(date +%F -d "$(stat -c %y "$FILENAME")")} I've also quoted the filenames so that they handle whitespace correctly.

Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
