If I commit and push code from several devices to a single repo in Github, is it possible to determine which commit came from which device?
Devices can be on the same or different networks.

Does a git commit metadata contain any unique identifier for the device, external identifiers such as ip address, or internally generated identifiers such as uuid?

I am asking this question out of curiosity, I don't intend to add such information to my commits.

git cat-file -p $thatcommitid prints the entirety of the commit metadata, that's literally all there is in it, zlib compressed with a type and length header showing that it's a commit and how long what you see printed is. So, no.

I have made a small research and found a great answer that might help in determine-which-computer-a-git-commit-came-from

No, but if you are looking to add this kind of information to your commits, you can either:

• use git notes
• use a pre-commit hook to automatically change the commit message to include the information you are after
