# Hah, I have almost the exact same thing in my bash_profile
    up () {
        TIMES=${1:-1};

        for ((i=1; i<=$TIMES; i++));
        do
            cd ..
        done
    }

EDIT: Although now I'm looking at it and it looks like I made a strange choice with `TIMES=${1:-1};`. Oh well, I think it was my first bash script... it's funny to look back at the hack-y crap that your bash_profile accumulates over time.
