Creating an alias would work as a temporary solution, however if you want something more permanent that doesn't confine you to your presets I suggest writing a function to do this and including it in your .bashrc file.

source

# Go up directory tree X number of directories

function up() {

        COUNTER="$@";

    # default $COUNTER to 1 if it isn't already set

if [[ -z $COUNTER ]]; then

    COUNTER=1

fi

# make sure $COUNTER is a number

if [ $COUNTER -eq $COUNTER 2> /dev/null ]; then

    nwd=`pwd` # Set new working directory (nwd) to current directory

    # Loop $nwd up directory tree one at a time

    until [[ $COUNTER -lt 1 ]]; do

        nwd=`dirname $nwd`

        let COUNTER-=1

    done

    cd $nwd # change directories to the new working directory

else

    # print usage and return error

    echo "usage: up [NUMBER]"

    return 1

fi

}
