pushd/popd

[Michael Havens]

I see. So it is a way to stack directories in your order so you can  go in
reverse a certain order and save yourself some typing. pushd is strange. if
you execute it alone it reverses the last two directories on your stack. I
didn't know about 'cd -'; thanks for sharing that with me.
