`find` is beautiful, no discussion. Together with tools like xargs there's hardly anything you can't do with it.

Following is slightly off-topic but for searching inside files like

    find . -name "*.css" -exec grep -l "#content" {} \;

try `ack` instead

    ack --css '#content'

Above command will recursively search for '#content' in all css files under the current directory. It is faster than grep and does automatically exclude your hidden version control folders. No need to mess with `--exclude`. I really stopped using grep at all. ack can be found here: http://betterthangrep.com/
