Be aware that this will rename your files from myFile to myFile.gz –  Kristof Provost Jul 30 '09 at 10:42

A simple, not very elegant bash script is to simply cd in, gzip them all in a loop, and mv them back (gzip by default removes the non-compressed file):

#!/bin/bash
cd myFolder
for f in `find ./ -type f`
do
    gzip $f
    mv $f.gz $f
done

Put that in a file called "gzip_and_rename.sh" for example, chmod -775 and run it like ./gzip_and_rename.sh (if running from within myFolder itself, remove the "cd myFolder" line from the script).

And yes I do know backticks are evil, but as I said this is just a quick hack script. –  Wesley Mason Jul 30 '09 at 10:50
    
why are backticks evil, what do you replace them with ? –  Anonymous Jul 30 '09 at 13:36

You could also try

 find myFolder -type f -exec gzip {} \; -exec mv {}.gz {} \;
