Stay in the loop…

Follow the Tweets.

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.

or, to process a single directory:

for f in *; do mv $f `echo $f |tr '[:upper:]' '[:lower:]'`; done
for i in *; do mv "$i" "$(echo $i|tr A-Z a-z)"; done

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.

find . -depth -print -execdir rename -f 'y/A-Z/a-z/' '{}' \;

easier way to recursively change files to lowercase using rename instead

zmv -Q '(**/)(*)(.)' '$1${(L)2}'

Example of zsh globing, glob qualifier, and substitution:

-Q state that the parameter will contain a glob qualifier.

(**/)(*) is recursive

(.) is our glob qualifier, with states the match is a file "."

The first parameter $1, is then substituted with $2 but with lowercasing '(L)' ... a (U) would of course be from lower to upper.

Know a better way?

If you can do better, submit your command here.
