Dirwalk is a shell-script function that lets you easily change your working directory to a given Git project.

I frequently find myself with a lot of Git repositories, and I want to be able to quickly change to the correct directory, without a lot of typing.

I can create a shell alias to change to the root directory, but how can I quickly change to the correct sub-directory, without a lot of typing?

Enter dirwalk!

Just type it, optionally with a regular expression, and it will find the correct sub-directory.

Note that this has to be a shell function, otherwise it will change the working directory of a child process, and then it will exit, leaving you where you started.

I prefer the fish shell, but I also wrote a Zsh version and Bash version. With some fiddling, you could probably get this to work with a more minimal shell, such as the original Bourne shell, or one of the lighter-weight shells such as ash. I may do so, when I find time.

I will be adding a ksh specific version soon. I may also see if I can consolidate the POSIX-ish shells, such as Zsh and Bash, into one script. However, currently there are some subtle differences between the shells that makes that challenging, e.g., zsh indexing arrays starting with 1, while Bash starts with 0, etc.
