查看git上的个人代码量：
git log --author="username" --pretty=tformat: --numstat | awk '{ add += $1; subs += $2; loc += $1 - $2 } END { printf "added lines: %s, removed lines: %s, total lines: %s\n", add, subs, loc }' -结果示例：(记得修改 username)
added lines: 120745, removed lines: 71738, total lines: 49007统计每个人增删行数
git log --format='%aN' | sort -u | while read name; do echo -en "$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结果示例

git log --pretty='%aN' | sort | uniq -c | sort -k1 -n -r | head -n 5贡献值统计
git log --pretty='%aN' | sort -u | wc -l提交数统计
git log --oneline | wc -l添加或修改的代码行数：
git log --stat|perl -ne 'END { print $c } $c += $1 if /(\d+) insertions/'使用gitstats
GitStats项目，用Python开发的一个工具，通过封装Git命令来实现统计出来代码情况并且生成可浏览的网页。官方文档可以参考这里。
使用方法
git clone git://github.com/hoxu/gitstats.git
cd gitstats
./gitstats 你的项目的位置 生成统计的文件夹位置可能会提示没有安装gnuplot画图程序，那么需要安装再执行：
//mac osx
brew install gnuplot
//centos linux
yum install gnuplot生成的统计文件为HTML：
使用cloc
npm install -g cloc
