CD hack with location history

I was in one who did not have this hack, and reminded me how useful it is. So I thought I would share it with others.

Some of you may know about pushd and popd. The pushd is like the cd, but it watches and remembers where you were. You can then display as many levels as you want. It's like a cd but it holds not just for the last time you used it.

The big problem I have with pushd and popd is that for popd to work, I have to remember to pushd first.

But, like most, from before, I issue commands in the terminal using the cd command. Until I realize that popd could be useful.

Now the hack.

Just pass the following code to ~ /.bashrc:
[pastacode manual=”function%20cd%0D%0A%7B%0D%0A%20%20%20%20if%20%5B%20%24%23%20-eq%200%20%5D%3B%20then%0D%0A%20%20%20%20%20%20%20%20pushd%20~%20%3E%20%2Fdev%2Fnull%0D%0A%20%20%20%20elif%20%5B%20%22%20%241%22%20%3D%20%22%20-%22%20%5D%3B%20then%0D%0A%20%20%20%20%20%20%20%20pushd%20%22%24OLDPWD%22%20%3E%20%2Fdev%2Fnull%0D%0A%20%20%20%20else%0D%0A%20%20%20%20%20%20%20%20pushd%20%22%24%40%22%20%3E%20%2Fdev%2Fnull%0D%0A%20%20%20%20fi%0D%0A%7D” provider=”manual” lang=”php”/] Και ξεκινήστε ένα νέο shell. Από εκείνο το σημείο και μετά, το cd θα τρέχει το pushd και το popd θα είναι πάντα when you need it.
