获取git mail的每个git提交下的文件

我正在尝试设置一个邮件客户端，每当git推送到中央回购时，它都会触发一封电子邮件。因此，我从中复制了脚本

这是我收到的推送邮件

 The project "My-Engineering":

    The branch, master has been updated
       via  e6693c90f2296a8df3bfcb13735cde069aababcd (commit)
       via  4e7e0176605a22b698e80f46b774abb1e721abcd (commit)

因此，我通过以下方式修改了上面链接中脚本中的代码：-

show_new_revisions()
{

    if [ "$change_type" = create ]
    then
        # Show all revisions exclusive to this (new) branch.
        revspec=$newrev
    else
        # Branch update; show revisions not part of $oldrev.
        revspec=$oldrev..$newrev
    fi

    other_branches=$(git for-each-ref --format='%(refname)' refs/heads/ |
    grep -F -v $refname)
    git rev-parse --not $other_branches |

    msg_count=0;
    git rev-list --pretty --stdin $revspec |
    while read onerev
    do
        # eval $(printf "$custom_showrev" onerev: $onerev)
        (( msg_count+=1 ))
        echo $msg_count
        if [ $msg_count == 5 ]
        then
            emailsubject="$onerev"
            echo "Files affected"
            git diff $oldrev..$newrev --name-status    #### Added this command 
            echo "$emailsubject" > "$emailsubject_tmp_file"
        fi
        echo "$onerev"
    done
}

但是，

git diff$oldrev..$newrev--name status

只有在推送下有两次提交时才能正常工作。如果我有2次以上的提交，那么对于每次提交，我都需要执行

git diff$current\u rev--name status

。 为此，我需要添加这段代码

 for rev in $(git rev-list $newrev..$oldrev)
    do
        echo "    $rev "
    done

但我无法添加它并使其工作。

谁能帮我解决这个问题。或者，建议是否有其他更好的方法，仅在具有多个提交的推送中的特定提交中显示更改
