Modifying the cd command
Hello everyone, I am currently doing a utility that acts like a cd command but keeps track of your change of directories.

What I plan to do is just to modify the cd source code, is that even possible? Can someone please help me with this?

I also need to incorporate the command with the history command.

Not a hope in hell.

(Sorry to be so blunt but the "cd" command is built into most modern Shells and modifying this command woud take the level of expertise afforded by Kernighan and Ritchie).

If you have a real commercial problem, please state the problem.

This has been done before. Do a web search for "pushd popd dirs"

Thank you so much for that, but I am having a problem implementing it. Uhm is it a built-in command already?
