我对上面的一个简短的回答作了修改，但这不足以满足我的需要。我需要能够对提交的行和最终代码中的行进行分类。我还想按文件进行细分。这段代码不递归，它只返回单个目录的结果，但如果有人想进一步了解，这是一个很好的开始。复制并粘贴到文件中并使其可执行或使用Perl运行。

这个脚本可以做到这一点。把它放入authorship.sh, chmod +x，就完成了。

#!/bin/sh
declare -A map
while read line; do
    if grep "^[a-zA-Z]" <<< "$line" > /dev/null; then
        current="$line"
        if [ -z "${map[$current]}" ]; then 
            map[$current]=0
        fi
    elif grep "^[0-9]" <<<"$line" >/dev/null; then
        for i in $(cut -f 1,2 <<< "$line"); do
            map[$current]=$((map[$current] + $i))
        done
    fi
done <<< "$(git log --numstat --pretty="%aN")"

for i in "${!map[@]}"; do
    echo -e "$i:${map[$i]}"
done | sort -nr -t ":" -k 2 | column -t -s ":"

除了Charles Bailey的回答之外，您可能还想在命令中添加-C参数。否则，即使文件内容没有被修改，文件重命名也会被视为大量的添加和删除(与文件的行数一样多)。

为了说明，当使用git log——oneline——shortstat命令时，这里有一个从我的一个项目中移动的大量文件的提交:

9052459 Reorganized project structure
 43 files changed, 1049 insertions(+), 1000 deletions(-)

这里使用git log——oneline——shortstat -C命令来检测文件的复制和重命名:

9052459 Reorganized project structure
 27 files changed, 134 insertions(+), 85 deletions(-)

在我看来，后者给出了一个人对项目有多大影响的更现实的观点，因为重命名一个文件比从头开始写文件要小得多。

这是一个伟大的回购，使您的生活更容易

我发现下面的方法对于查看当前代码库中谁拥有最多的行很有用:

git ls-files -z | xargs -0n1 git blame -w | ruby -n -e '$_ =~ /^.*\((.*?)\s[\d]{4}/; puts $1.strip' | sort -f | uniq -c | sort -n

其他答案主要集中在提交中更改的行，但如果提交无法存活并被覆盖，则它们可能只是被更改了。上面的咒语还可以让您按行对所有提交者进行排序，而不是一次只排序一个。您可以向git blame (-C -M)添加一些选项，以获得一些更好的数字，将文件移动和文件之间的行移动考虑在内，但如果这样做，该命令可能会运行更长时间。

同样，如果你正在为所有提交者寻找在所有提交中更改的行，下面的小脚本很有帮助:

http://git-wt-commit.rubyforge.org/#git-rank-contributors

要统计给定作者(或所有作者)在给定分支上提交的数量，可以使用git-shortlog;特别是它的——编号和——摘要选项，例如在git存储库上运行时:

$ git shortlog v1.6.4 --numbered --summary
  6904  Junio C Hamano
  1320  Shawn O. Pearce
  1065  Linus Torvalds
    692  Johannes Schindelin
