lc, or "List Commands used in this directory". It's a bash_history that's directory specific, because the terminal commands I type are usually directory-specific. It is only like 10 lines of bash, and I got help with the bash, but I'm proud of it and I use it everyday. I think my most common usage is `lc | grep partialCommandIcCantQuiteRemember`
