ack

My top tip right now for any command line cowboys (like me) is to install “ack” as it’s saving me time and irritation. http://betterthangrep.com/

It is for searching for exact terms or regexps in a directory tree, just like grep -r, but with all the .svn and other crap filtered out. Many people I know have written their own hacky tools to do this, but “ack” is a better solution.
