Remove committer information from git commits

问题

I have rebased a branch and now all its commits have committer section which I would like to remove completely (not just changing it's fields). Is it possible without losing the original author info?

回答1:

Thanks to @sergej and GitHub, I got committer info removed with

git filter-branch --env-filter '
if [ "$GIT_COMMITTER_EMAIL" != "$GIT_AUTHOR_EMAIL" ]; then
  export GIT_COMMITTER_NAME="$GIT_AUTHOR_NAME"
  export GIT_COMMITTER_EMAIL="$GIT_AUTHOR_EMAIL"
  export GIT_COMMITTER_DATE="$GIT_AUTHOR_DATE"
fi
' --tag-name-filter cat -- --branches --tags

You have to rewrite the history.

GitHub has a script that does that, see Changing author info.

It should be straight forward to adopt it to your needs:

#!/bin/sh

git filter-branch --env-filter '

OLD_EMAIL="your-old-email@example.com"
CORRECT_NAME="Your Correct Name"
CORRECT_EMAIL="your-correct-email@example.com"

if [ "$GIT_COMMITTER_EMAIL" = "$OLD_EMAIL" ]
then
    export GIT_COMMITTER_NAME="$CORRECT_NAME"
    export GIT_COMMITTER_EMAIL="$CORRECT_EMAIL"
fi
if [ "$GIT_AUTHOR_EMAIL" = "$OLD_EMAIL" ]
then
    export GIT_AUTHOR_NAME="$CORRECT_NAME"
    export GIT_AUTHOR_EMAIL="$CORRECT_EMAIL"
fi
' --tag-name-filter cat -- --branches --tags
