git 批量修改邮箱，注意修改 TARGET_NAME CORRECT_NAME CORRECT_EMAIL 字段

git filter-branch -f --env-filter '
TARGET_NAME="Old Name"
CORRECT_NAME="username"
CORRECT_EMAIL="ID+username@users.noreply.github.com"

# 检查提交者的名字是否匹配
if [ "$GIT_COMMITTER_NAME" = "$TARGET_NAME" ]
then
    export GIT_COMMITTER_NAME="$CORRECT_NAME"
    export GIT_COMMITTER_EMAIL="$CORRECT_EMAIL"
fi

# 检查作者的名字是否匹配
if [ "$GIT_AUTHOR_NAME" = "$TARGET_NAME" ]
then
    export GIT_AUTHOR_NAME="$CORRECT_NAME"
    export GIT_AUTHOR_EMAIL="$CORRECT_EMAIL"
fi
' --tag-name-filter cat -- --branches --tags

推送（请勿在生产环境操作）：git push origin --force --all git push origin --force --tags
