Yeah, running the command that way seems like an appropriate solution. I’ll give it a try; thanks!
As for why the commands can’t be run in parallel given they are read-only, I’m not sure, but since git clang-format is an extenstion of Git’s CLI (a python script called git-clang-format), it’s possible that the script doesn’t indicate that it is read-only, or that Git just doesn’t support having multiple processes running on the same repo.
