在看了Alex和Gerty3000的答案后，我试着缩短了一行字:

基本上，使用git log numstat，而不跟踪更改的文件数量。

Mac OSX上的Git 2.1.0版本:

git log --format='%aN' | sort -u | while read name; do echo -en "$name\t"; git log --author="$name" --pretty=tformat: --numstat | awk '{ add += $1; subs += $2; loc += $1 - $2 } END { printf "added lines: %s, removed lines: %s, total lines: %s\n", add, subs, loc }' -; done

例子:

Jared Burrows   added lines: 6826, removed lines: 2825, total lines: 4001

对于windows用户，可以使用以下批处理脚本计算指定作者添加/删除的行数

@echo off

set added=0
set removed=0

for /f "tokens=1-3 delims= " %%A in ('git log --pretty^=tformat: --numstat --author^=%1') do call :Count %%A %%B %%C

@echo added=%added%
@echo removed=%removed%
goto :eof

:Count
  if NOT "%1" == "-" set /a added=%added% + %1
  if NOT "%2" == "-" set /a removed=%removed% + %2
goto :eof

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。

吉特名声

这是一个很好的工具，可以一次性获得所有作者的计数，包括提交和修改文件的计数:

sudo apt-get install ruby-dev
sudo gem install git_fame
cd /path/to/gitdir && git fame

https://github.com/casperdcl/git-fame上也有Python版本(@fracz提到过):

sudo apt-get install python-pip python-dev build-essential 
pip install --user git-fame
cd /path/to/gitdir && git fame

样例输出:

Total number of files: 2,053
Total number of lines: 63,132
Total number of commits: 4,330

但是要注意的是:正如Jared在评论中提到的，在一个非常大的存储库上做这件事将花费数小时。但考虑到它必须处理如此多的Git数据，不确定是否可以改进。

使用以下方法将日志保存到文件:

git log --author="<authorname>" --oneline --shortstat > logs.txt

对于Python爱好者:

with open(r".\logs.txt", "r", encoding="utf8") as f:
    files = insertions = deletions = 0
    for line in f:
        if ' changed' in line:
            line = line.strip()
            spl = line.split(', ')
            if len(spl) > 0:
                files += int(spl[0].split(' ')[0])
            if len(spl) > 1:
                insertions += int(spl[1].split(' ')[0])
            if len(spl) > 2:
                deletions += int(spl[2].split(' ')[0])

    print(str(files).ljust(10) + ' files changed')
    print(str(insertions).ljust(10) + ' insertions')
    print(str(deletions).ljust(10) + ' deletions')

你的输出是这样的:

225        files changed
6751       insertions
1379       deletions

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。
