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
    443  Eric Wong

下面是一个快速ruby脚本，针对给定的日志查询汇总每个用户的影响。

例如rubinius:

Brian Ford: 4410668
Evan Phoenix: 1906343
Ryan Davis: 855674
Shane Becker: 242904
Alexander Kellett: 167600
Eric Hodel: 132986
Dirkjan Bussink: 113756
...

脚本:

#!/usr/bin/env ruby

impact = Hash.new(0)

IO.popen("git log --pretty=format:\"%an\" --shortstat #{ARGV.join(' ')}") do |f|
  prev_line = ''
  while line = f.gets
    changes = /(\d+) insertions.*(\d+) deletions/.match(line)

    if changes
      impact[prev_line] += changes[1].to_i + changes[2].to_i
    end

    prev_line = line # Names are on a line of their own, just before the stats
  end
end

impact.sort_by { |a,i| -i }.each do |author, impact|
  puts "#{author.strip}: #{impact}"
end

一个解决方案是ruby在中间，perl是一个更可用的默认情况下，这里是一个替代使用perl当前行作者。

git ls-files -z | xargs -0n1 git blame -w | perl -n -e '/^.*\((.*?)\s*[\d]{4}/; print $1,"\n"' | sort -f | uniq -c | sort -n

你想责怪Git。

有一个——show-stats选项来打印一些统计数据。

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。

#!/usr/bin/perl

以下命令的输出应该很容易发送到脚本，以计算总数:

git log --author="<authorname>" --oneline --shortstat

这将提供当前HEAD上所有提交的统计信息。如果你想在其他分支中添加统计数据，你必须将它们作为参数提供给git log。

对于传递到脚本，即使删除“一行”格式也可以使用空日志格式完成，正如Jakub narabulbski所评论的那样，——numstat是另一种替代方法。它生成每个文件而不是每个行统计数据，但更容易解析。

git log --author="<authorname>" --pretty=tformat: --numstat
