I was searching for something to help me manage the multiple git folders in my ~/dust/code directory, and see quickly which ones have new versions that could be pulled, and came across clustergit which does exactly what I was looking for.
This definitely beats my messy bash for loop, hah. Stoked to try this out, thanks for sharing!
If I ever get to the point where I can finish my git guide for Norns admin like that sftp guide I wrote, this seems like a potentially cool thing to mention at the end.
