as alternative to cd $OLDPWD
if you cd into a directory then cd into another directory somewhere else then you run the cd - command you will go to the previous directory you was in!! To go back to the other directory just run it again. So if you are working in 2 different directories then this is the perfect command for you.
Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
