一行代码，但如果您有一个多用户存储库，请小心——这会将所有提交更改为具有相同的（新的）作者和提交人。

git filter-branch -f --env-filter "GIT_AUTHOR_NAME='Newname'; GIT_AUTHOR_EMAIL='new@email'; GIT_COMMITTER_NAME='Newname'; GIT_COMMITTER_EMAIL='new@email';" HEAD

字符串中有换行符（这在bash中是可能的）：

git filter-branch -f --env-filter "
    GIT_AUTHOR_NAME='Newname'
    GIT_AUTHOR_EMAIL='new@email'
    GIT_COMMITTER_NAME='Newname'
    GIT_COMMITTER_EMAIL='new@email'
  " HEAD

如果您想（轻松）更改当前分支的作者，我会使用类似的方法：

# update author for everything since origin/master
git rebase \
  -i origin/master \
  --exec 'git commit --amend --no-edit --author="Author Name <author.name@email.co.uk>"'

GitHub最初有一个很好的解决方案（断开链接），它是以下shell脚本：

#!/bin/sh

git filter-branch --env-filter '

an="$GIT_AUTHOR_NAME"
am="$GIT_AUTHOR_EMAIL"
cn="$GIT_COMMITTER_NAME"
cm="$GIT_COMMITTER_EMAIL"

if [ "$GIT_COMMITTER_EMAIL" = "your@email.to.match.example" ]
then
    cn="Your New Committer Name"
    cm="Your New Committer Email"
fi
if [ "$GIT_AUTHOR_EMAIL" = "your@email.to.match.example" ]
then
    an="Your New Author Name"
    am="Your New Author Email"
fi

export GIT_AUTHOR_NAME="$an"
export GIT_AUTHOR_EMAIL="$am"
export GIT_COMMITTER_NAME="$cn"
export GIT_COMMITTER_EMAIL="$cm"
'

我也想添加我的示例。我想用给定的参数创建一个bash_function。

这在mint-linux 17.3中有效

# $1 => email to change, $2 => new_name, $3 => new E-Mail

function git_change_user_config_for_commit {

 # defaults
 WRONG_EMAIL=${1:-"you_wrong_mail@hello.world"}
 NEW_NAME=${2:-"your name"}
 NEW_EMAIL=${3:-"new_mail@hello.world"}

 git filter-branch -f --env-filter "
  if [ \$GIT_COMMITTER_EMAIL = '$WRONG_EMAIL' ]; then
    export GIT_COMMITTER_NAME='$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;
}

这不是对你问题的回答，而是一个脚本，你可以用它来避免将来发生这种情况。它利用Git 2.9版以来可用的全局钩子，根据您所在的目录检查您的电子邮件配置：

#!/bin/sh
PWD=`pwd`
if [[ $PWD == *"Ippon"* ]] # 1)
then
  EMAIL=$(git config user.email)
  if [[ $EMAIL == *"Work"* ]] # 2)
  then
    echo "";
  else
    echo "Email not configured to your Work email in the Work directory.";
    git config user.email "youremail@youremail.com"
    echo "Git email configuration has now been changed to \"$(git config user$
    echo "\nPlease run your command again..."
    echo ''
    exit 1
  fi;
elif [[ $PWD == *"Personal"* ]]
then
  EMAIL=$(git config user.email)
  if [[ $EMAIL == "youremail@youremail.com" ]]
  then
    echo "";
  else
    echo "Email is not configured to your personal account in the Personal di$
    git config user.email "youremail@youremail.com"
    echo "Git email configuration has now been changed to \"$(git config user$
    echo "\nPlease run your command again..."
    echo ''
    exit 1;
  fi;
fi; 

它检查您当前的工作目录，然后验证您的git是否配置为正确的电子邮件。如果没有，它会自动更改。请在此处查看详细信息。

如果您要修复的提交是最新的，并且只有几个，您可以使用git reset和git stash的组合，在配置正确的名称和电子邮件后再次提交。

顺序如下（对于2个错误的提交，没有挂起的更改）：

git config user.name <good name>
git config user.email <good email>
git reset HEAD^
git stash
git reset HEAD^
git commit -a
git stash pop
git commit -a
