[ale] xargs w/ tr

[David S. Jackson]

I was just experimenting with xargs and tr and wondered why the
following didn't work as expected:

locate *.{mp3,MP3} | xargs -I % mv % `echo %|tr A-Z a-z`

What happens is the second % doesn't seem to get tr'ed.  Any idea why?

I know there are lots of other ways to do this, but I'm just curious
about why tr doesn't seem to work here (or maybe it's xargs...).
