How to get (only) author name or email in git given SHA1?

Question

I would like to check for author\'s e-mail and name, surname to verify who\'s pushing to my repo.

Is there any way that I can come up with a command in git to show c

Answer 1

git show <commit_id> | grep Author

Using git show + pipe + grep works!

Answer 2

You can use the following command:

 git log --format='%ae' HASH^!

It works with git show as well. You need to include -s to suppress the diff.

git show -s --format='%ae' HASH
