You cd around like you normally would, and the directories are pushed into a stack. Use the function s to view the stack of directories, and run s "$num" to cd into the directory listed. Use b to jump back 1 directory.

I was inspired by this article written by Derek Wyatt about directory management in BASH. The code I’ve written for this accomplishes most of the same tasks, but does so with about 1/3 of the code, as this was written specifically for BASH (no legacy KSH bits) and doesn’t implement any of the fancier features for cd.

Example

In the above example I cd around a bit, and then run s to see what the current stack looks like. The current stacks shows all of my previous directories in reverse order (limited to $CD_STACK_MAX entries, which defaults to 15).
