Changing the Git history

After a month of having formatted my work computer, I noticed that my mail configured in GIT was wrong. This caused my commits to not recognize me as the author and not appear on my account activity.

If this error is detected after a single commit, it can be easily solved with the following command:

git commit --amend --author="Correct Name <[e-mail]>"

If it is detected after several commits, as happened to me, the best solution is this:

	#!/bin/sh
	git filter-branch --env-filter '
	OLD_EMAIL="[e-mail]"
	CORRECT_NAME="Your Correct Name"
	CORRECT_EMAIL="[e-mail]"
	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
