Quickly navigate your filesystem from the command line

I had to modify Jeroen's code to get the `marks` shortcut working under Mac OS 10.8:

    export MARKPATH=$HOME/.marks
    function jump {
        cd -P $MARKPATH/$1 2> /dev/null || echo "No such mark: $1"
    }
    function mark {
        mkdir -p $MARKPATH; ln -s $(pwd) $MARKPATH/$1
    }
    function unmark {
        rm -i $MARKPATH/$1
    }
    function marks {
        ls -l $MARKPATH | sed 's/  / /g' | cut -d' ' -f9- && echo
    }

    brew install fasd

Thank me later

You can also use ranger [1] to change directories, especially if you want to explore the directory tree quickly when you don't know exactly where to jump to. Install it and add the following to ~/.bashrc:

     function ranger-cd {
       tempfile='/tmp/chosendir'
       /usr/bin/ranger --choosedir="$tempfile" "${@:-$(pwd)}"
       test -f "$tempfile" &&
       if [ "$(cat -- "$tempfile")" != "$(echo -n `pwd`)" ]; then
         cd -- "$(cat "$tempfile")"
       fi
       rm -f -- "$tempfile"
     }

     # This binds Ctrl-O to ranger-cd:
     bind '"\C-o":"ranger-cd\C-m"'

(This script comes from the man page for ranger(1).)

Edit: Modified the above script for use with zsh (and multiple users):

     ranger-cd() {
       tempfile=$(mktemp)
       ranger --choosedir="$tempfile" "${@:-$(pwd)}"
