Setting user data just for one commit

I don’t have the git user data set:

$ git commit -m '...'

*** Please tell me who you are.


  git config --global ""
  git config --global "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

fatal: empty ident name (for <...>) not allowed

If I run these commands my user data will be set globally. I only want to have the user data set for one commit.

    The --author flag will set the author, but you must also set the committer name and email.

    There is no command-line flag for this but git will use environment variables if they are set: GIT_COMMITTER_NAME and GIT_COMMITTER_EMAIL.

    Assuming an sh/bash-style shell:

    GIT_COMMITTER_EMAIL='author@example.example' \
    git commit --author 'A U Thor <author@example.example>' ...

    should do it.

    Or, you can just set these in your git global configuration, then remove them (use git config --global -e to run your favorite editor on the file, if you don’t want to fiddle with git config --unset).

    Edit: or, you can configure them temporarily with git -c name=value, e.g.:

    git -c'A U Thor' -c commit ...

    Note that (as with the environment variables) this will override any file-configuration values.

    You can specify the author using the --author option:

    git commit --author="Corey Ward <>" -m "..."

    Author can be overridden by using the –author option
