j, a cd command that learns
This one's for the unix nerds; everyone else can move along. Spend a lot of time cd-ing around a complex directory tree? j keeps track of where you’ve been, and how much time you spend there. Source it into your .bashrc, and then you can say j foo to jump to the most used directory that has the substring (actually regex) foo in it, or j foo bar for the directory that has both foo and bar ...

There's been some discussion on reddit about this, but I thought some Mefi people might want to know about it.

This tool is by Mefi's 31d1; I've been helping debug it a bunch.

It's like there's a party in my bash history, and only the most popular substring matches are invited.

Wow, this is way better than pushd and popd. The nice thing is that it's easy to move the script around -- I work on 4 or 5 different linux servers, so this is my primary concern with new shell features.

This sounds like a great idea. I'll be trying it out on several servers.
