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

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

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

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

这是一个伟大的回购，使您的生活更容易

在安装了brew的mac上

酿造安装git-quick-stats

Run

git-quick-stats

只需从这个列表中输入列出的数字并按enter键，选择您想要的选项。

 Generate:
    1) Contribution stats (by author)
    2) Contribution stats (by author) on a specific branch
    3) Git changelogs (last 10 days)
    4) Git changelogs by author
    5) My daily status
    6) Save git log output in JSON format

 List:
    7) Branch tree view (last 10)
    8) All branches (sorted by most recent commit)
    9) All contributors (sorted by name)
   10) Git commits per author
   11) Git commits per date
   12) Git commits per month
   13) Git commits per weekday
   14) Git commits per hour
   15) Git commits by author per hour

 Suggest:
   16) Code reviewers (based on git history)

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 ":"
