Change author username email from previous already pushed commits | history

editPreviousCommitAuthorEmailUsername.md

git filter-branch -f --env-filter '
WRONG_EMAIL="<wrong_email>"
NEW_NAME="<username>"
NEW_EMAIL="<your_email>"
    
if [ "$GIT_COMMITTER_NAME" = "De Backer Christophe" ]

then
    export GIT_COMMITTER_NAME="$NEW_NAME"
    export GIT_COMMITTER_EMAIL="$NEW_EMAIL"
fi

if [ "$GIT_AUTHOR_EMAIL" = "$WRONG_EMAIL" ]

then
    export GIT_AUTHOR_NAME="$NEW_NAME"
    export GIT_AUTHOR_EMAIL="$NEW_EMAIL"
fi
' --tag-name-filter cat -- --branches --tags 

Then you need to use git push -f <remote> <branch>

And if I want to delete a commit from the history ?

1. git log to find the commit you want to remove and copy its hash

2. git rebase -i <commit_hash>~ which opens your text editor

3. In text editor, switch from pick to drop for your particular commit

4. Then you may want to use an git rebase --continue
