[NTLUG:Discuss] Any idea of pop utilities

[Pervaz Allaudin]

I do not remember exactly when and where but I saw this demo where a guy 
was switching between subdirs using a command like push and pop. Where 
push dir worked like cd and pop brought him back to original. (I do not 
recall if he just popped again to return to the last one.)

Every time I have to switch back and forth between dirs I remember this. 
I looked for it but could not find it.

As you can tell I am novice enough not to be able to make one in bash 
shell on the fly. I probably could with a bit of an effort and a day or 
two but Anybody know where I can get this or anything similar.
