Grappling Hook

While navigating through projects in the terminal, I always wished there was a way to just return to the root directory of the project without having to think so much about how many ..s to use in your cd. Sort of like a cd - but a bit smarter. That was the inspiration for this project.

All it is is just a shell script that keeps going up from your working directory to its parent directories until it finds one with a .git subdirectory. Since a shell subprocess cannot perform cds, the script only echos the right directory and you must add a function in your bash file to cd using the output of the shell script. In my case I named this function hook.

In addition to just taking you to the parent directory with a .git subdirectory, you can also pass an extra variable equal to the name of a directory in the path from your working directory to the parent directory to be cd‘d into that directory instead.
