People have already suggested variants on this:

  for x in *; do mv $x `echo $x | tr '[A-Z]' '[a-z]'`; done

You could also install the mmv package and try this instead:

  mmv '*' '#l1'

... or this:

  mmv \* \#l1

... depending on what quoting style you prefer. Using backquotes allows
you to do more general transformations, though.

You might also try rename, which comes with the perl-5.005 package.

HTH,
