If you want to nitpick... The result of a Windows user getting confused
about extensions:

[James at kendrick JPEGs]$ ls
badly-named.JPG.JPG
[james at kendrick JPEGs]$ rename .JPG .jpg *.JPG
[james at kendrick JPEGs]$ ls
badly-named.jpg.JPG

More UNIXy, and one I haven't seen yet:
[james at kendrick JPEGs]$ ls
badly-named.JPG.JPG
[james at kendrick JPEGs]$ for i in *.JPG ; do mv $i $(basename $i .JPG).jpg ; done
[james at kendrick JPEGs]$ ls
badly-named.JPG.jpg

basename will strip off any leading directory components, and optionally
any suffix.

Hope this helps,

James.
