back-forward functionality in 'cd'

[Arjun Shankar]

Hi!

Someone just handed me a nifty bit of shell script that works like
'cd', with the added advantage of being able to go back and forward
('cd ]' takes you forward, and 'cd [' takes you back to the last
directory), just like text based file browsers (nautilus etc).
Basically, It is something better than 'cd -'. Wouldn't it be a good
idea to include it as an option in the actual 'cd'? I think such an
option makes for much easier directory traversal. I believe POSIX does
not allow this, and that you would like to stick with what you got
already, but I guessed you would consider this, because it makes
things a lot easier.
Thanks,
Arjun Shankar.
