Git - Author


The author is the person who originally wrote the code or the patch.

The author date is also referred to as the commit date.


The default author in git is in order of precedence:

  • the global user
git config --global "Your Name"
git config --global [email protected]
  • the environment variable EMAIL,
  • the system user name and the hostname used for outgoing mail (/etc/mailname)
  • the fully qualified hostname

How to define the author in a commit?

Git - Commit

git commit --author="Name <email>" -m "whatever"
# modification of the last commit, -C HEAD to not modify the message
git commit --amend --author='Name <email>' -C HEAD

Note that author information is taken from the following environment variables, if set:


How to set the author date?

# Give a date to the commit
git commit --date='Wed Feb 16 14:00 2037 +0100'
git commit --date='2005-04-07T22:13:13' # Iso

# Change the date of a previous commit
# The -C HEAD is just to bypass editing the commit message
git commit --amend --date='Wed Feb 16 14:00 2037 +0100' -C HEAD
