Two bash functions which save me many key strokes.

Do automatically an ls after every successfull cd:

function cd { builtin cd "$@" && ls } 

Go up n levels:

# Usage .. [n] function .. (){ local arg=${1:-1}; local dir="" while [ $arg -gt 0 ]; do dir="../$dir" arg=$(($arg - 1)); done cd $dir #>&/dev/null }
