You can also use the "dirs" command (I think part of bash as well) that tells you the state of the stack. If you set the -v option, you can get the depth of different directories, and you can just do pushd +N to jump to the specific directory.

funny- I don't see man pages (nor info pages) for pushd, popd, or dirs. What am I missing about the documentation?

They're shell built-ins, so use "man bash" to read about them.

To only display information about a specific command, you can also use

    help <command>

Awesome. Thanks.
