Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

convert filenames in current directory to lowercase

The simplest way I know.

recursively change file name from uppercase to lowercase (or viceversa)

or, to process a single directory:

for f in *; do mv $f `echo $f |tr '[:upper:]' '[:lower:]'`; done

convert filenames in current directory to lowercase

This will convert filenames from uppercase to lowercase. I find this useful after downloading images from my digital camera. This works for English, but other languages may need something slightly more complex like this:

for i in *; do mv "$i" "$(echo $i|tr [:upper:] [:lower:])"; done

Also, the quote marks aren't necessary if your filenames don't contain spaces.

Know a better way?

If you can do better, submit your command here.

What others think

This works great and is the simplest way to perform this task if you have the rename command available which is part of PERL.

One downside is that this command isn't recursive, but I still gave it a thumbs up.
