As Junio said, the "--author=<author name and email>" sets the author identity, but not the committer identity; you can work around the issue with "git -c user.name=me -c user.email=me@xxxxxxxx". In Git the commit stories both the author and the committer. The author is the person who made the changes, the committer is the person who entered the changes into repository (created a commit object). You might want to enter into your repository changes made by somebody else (that you for example got as a patch): that is what --author is for. Better though is to focus on what you want, namely to prevent accidental commits without specified author, instead of how you want to achieve it, i.e. using --author to provide both author and committer identity (the XY problem). On that machine with "automatic test account" set up pre-commit or commit-msg hook that fails if the GIT_AUTHOR_IDENT environment variable is not the "automatic test account". Hope that helps, -- Jakub Narębski
