Ruby script to recursively svn up/git pull your sources directory

Do you have a directory full of checkouts of other people’s projects? For reference, for contribution work, etc?

Wouldn’t you like to update them all at once?

Here’s a basic ruby script that you should run at the root level of your “sources” directory. It will go through the directory, find all the folders, check if they’re under source control (supports svn, git and bzr) and if so, attempts to update them.

It’s not very nice to look at, but it’s saved me a lot of time, and I can’t find anything similar around so I thought I’d release it here. Please tell me if you have any suggestions or improvements.

I know you might think it’s strange to put a copyright license on such a small script but it’s for your protection, not mine. I’ve seen copyright claims over lesser things. By explicitly releasing software code, no matter how simple, you can rest easy in its use anywhere. I wish everyone included licenses with everything; I’d feel a lot more comfortable using things I find on the net if it’s been explicitly released in this manner.
