Change author and email address in Git

enter image description hereI was changing the git author information inside the terminal and for whatever reason the update has removed the email from the commit and now I am unable to revert this change and can't add an email address to this commit.

The commit includes an author that I can't amend and the email linked to the commit is <>.

Can someone please advise how I can add an email address to this author?

You can batch change the commit history with the nuclear option git filter-branch. Using --env-filter, you can change author and email info. See Changing Author Info - GitHub for more info. Since you don't have an email info now, you may catch the messy name for judging the necessity of rewriting.

For example,

#!/bin/sh
git filter-branch -f --env-filter '
OLD_NAME="Your messy name" # you may need to escape the " char in the head and tail of that messy
CORRECT_NAME="MatthewLRichardson"
CORRECT_EMAIL="[email protected]"
if [ "$GIT_COMMITTER_NAME" = "#OLD_NAME" ]
then
    export GIT_COMMITTER_NAME="$CORRECT_NAME"
    export GIT_COMMITTER_EMAIL="$CORRECT_EMAIL"
fi
if [ "$GIT_AUTHOR_NAME" = "#OLD_NAME" ]
then
    export GIT_AUTHOR_NAME="$CORRECT_NAME"
    export GIT_AUTHOR_EMAIL="$CORRECT_EMAIL"
fi
' --tag-name-filter cat -- --branches --tags

Then, do a force push, and tell your collaborator to update their fork, if there exists some.
