Here's a simple but handy way to convert files (and directories) to lowercase.
If you're moving data from a Windows environment, this can be especially handy.
Note: Be careful when using. It has no checks or options... it simply changes any
file or directory (where you have permission) to all lowercase.

I put scripts in a directory in my home that is in my PATH. Be sure to change
the file to executable.
Code:
#!/bin/bash
# Script to convert filenames/directories to lowercase
#
for f in *; do
  mv $f `echo $f | tr '[A-Z]' '[a-z]'`
done


I saw it on another forum, thought it handy enough to post here.

looks interesting.. maybe when i am bored to death at work i will write a version in Python and put in some checks and so on..

make sure that you actually dont rename files that are supposed to have a mix of lower and upper case characters..

Good point.... but mainly I think it would be useful for converting files from a windows
drive where case wouldn't matter. This is not really a tool to be used on system files.

Why not just use rename, which is part of perl in Debian (don't know about Gentoo, waiting until I get broadband to try it):
Code:
rename 'y/[A-Z]/[a-z]/' filename

It's also useful for replacing underscores in filenames with spaces:
Code:
rename 's/_/ /g' filename
Crucial with abcde, I think.

If rename is part of perl, then this would be for those that don't have/want perl ;)
Didn't know rename existed, thanks for the tip.

"abcde" is an all-in-one command-line cd encoding tool. I've just discovered it thanks to hilker's post. It seems very cool, but this is quite off-topic...

The point is it generates filenames (from cddb queries) which are full of underscores, and I think that's why hilker use his "rename" command on it.
