More grep
I needed to remember how to find a grep command that I used in the past so I did a Ctrl + r and then typed in grep and I found I had used grep -rco "searchterm" and then whaterver I searched for. So I have to be in the directory that all the files I need to search in are in, which is a bit of a hassle, but its quick and shows me count of how many occurances the word is in each file....
