You will need to use filter-branch
<!-- language: lang-bash -->
git filter-branch --commit-filter '
if [ "$GIT_COMMITTER_NAME" = "<Old Name>" ];
then
GIT_COMMITTER_NAME="<New Name>";
GIT_AUTHOR_NAME="<New Name>";
GIT_COMMITTER_EMAIL="<New Email>";
GIT_AUTHOR_EMAIL="<New Email>";
git commit-tree "$@";
else
git commit-tree "$@";
fi' HEAD `
If you are the **ONLY** user who committed to this repository you can simply update all references without checking the old content
<!-- language: lang-bash -->
git filter-branch -f --env-filter '
GIT_AUTHOR_NAME="Newname"
GIT_AUTHOR_EMAIL="newemail"
GIT_COMMITTER_NAME="Newname"
GIT_COMMITTER_EMAIL="newemail"
' HEAD
You can also do:
<!-- language: lang-bash -->
git filter-branch --commit-filter '
if [ "$GIT_COMMITTER_NAME" = "<Old Name>" ];
then
GIT_COMMITTER_NAME="<New Name>";
GIT_AUTHOR_NAME="<New Name>";
GIT_COMMITTER_EMAIL="<New Email>";
GIT_AUTHOR_EMAIL="<New Email>";
git commit-tree "$@";
else
git commit-tree "$@";
fi' HEAD
Note, if you are using this command in the Windows command prompt, then you need to use `"` instead of `'`:
<!-- language: lang-bash -->
git filter-branch --commit-filter "
if [ "$GIT_COMMITTER_NAME" = "<Old Name>" ];
then
GIT_COMMITTER_NAME="<New Name>";
GIT_AUTHOR_NAME="<New Name>";
GIT_COMMITTER_EMAIL="<New Email>";
GIT_AUTHOR_EMAIL="<New Email>";
git commit-tree "$@";
else
git commit-tree "$@";
fi" HEAD
