问题
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 commiter's name/e-mail given only SHA1 of the commit?
This is what I came up with but it's far from ideal solution (the first solution is for git hook that's why it's using 2 SHA1s with rev-list. The second one simply uses git show):
git rev-list -n 1 --pretty=short ccd3970..6ddf170 | grep Author | cut -d ' ' -f2- | rev | cut -d ' ' -f2- | rev
git show 6ddf170 | grep Author | cut -d ' ' -f2- | rev | cut -d ' ' -f2- | rev

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
回答2:
git show <commit_id> | grep Author
Using git show + pipe + grep works!
