Autocomplete from any folder using CDPATH

The magic of CDPATH

Bashs man page describes what the `CDPATH variable does.

The search path for the cd command. This is a colon-separated list of directories in which the shell looks for destination directories specified by the cd command. A sample value is “.:~:/usr”.

This means that if we add our ~/Sites folder to CDPATH we will be able to just type cd project-name instead of cd ~/project-name. OS X uses ~/.bash_profile to load predefined variables and function so this is where we’ll add our CDPATH modifications.

The code below will add your ~/Sites to CDPATH keeping any other changes you might have done with it. After this you should be able to cd project-name from a terminal (remember that you’ll need to restart terminal or do an export on the CDPATH changes before it will start working).

Use your favorite code editor to open ~/.bash_profile and add the following.

CDPATH=$CDPATH:~/Sites/

bash-completion gives you back tab completion.

This is great! Now I just need to type the project name to go to it. But I’m actually even more lazy, I want tab completion as well. Enter bash-completion. Sadly bash-completion isn’t installed by default to OS X (at least not my install of OS X 10.6). To install this we need some kind of ports system. I decided that this would be a great time to try out the new solution called Homebrew. From what I’d read about it it was supposed to be simpler than the alternatives Fink and MacPorts.

Homebrew, a great ports solution

Installing homebrew was extremely simple and I was up and running fast. Sadly homebrew have some requirements that might take you longer to get working (no exception for homebrew, the same goes for Fink as well as MacPorts). But instead of me copy/pasting the homebrew installation instructions just read them from homebrews page.

Once you have Homebrew up and running installing bash-completion is as simple as

brew install bash-completion

The bash-completion installer wanted me to add a couple of lines to my .bash_profile file.

if [ -f `brew --prefix`/etc/bash_completion ]; then
  . `brew --prefix`/etc/bash_completion
fi
