Counting files within folder (sub-folder). Shell or Ruby?

I was trying to count how many .java I had in one specific project. At first I tried using shell commands to do it but I find that I could do a easier task with Ruby.

Dir["/Users/celsodantas/code/java/src/**/*.java"].count

There we go. It will go through all sub-folders and return an array of all files. For me it's easier to remember this then a command shell command like:

find . -type f | wc -l

Some people might find easier to go with shell. I'm lazy and tend to go with what I remember more quickly. Feel free to chose what you feel more comfortable.

cheers!
