My script doesn't nicely handle the case where the the file already has the proper name. In those cases, mv will complain about target and source being the same file. To prevent that, simply change the for:
Code:
for file in [a-z]* ;do

As far as a "pure" bash solution, I don't think one exists without writing a big case-Waac to handle lower - upper case conversion. Luckily, cut and tr are standard tools on every system. But it's pretty cool to see how ruby is apt for more than just Web Development.
