关于个人或项目git仓库代码统计的常用命令

查看git上个人代码量：
 
git log --author=<user_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 }' -

统计每个人的增删行数：
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


查看仓库提交者排名前 5：
git log --pretty='%aN' | sort | uniq -c | sort -k1 -n -r | head -n 5

贡献者统计：
git log --pretty='%aN' | sort -u | wc -l

提交数统计：
git log --oneline | wc -l 

统计23个周内所有的代码行数：
git log --pretty=tformat: --numstat --since="23 weeks ago" | awk '{ add += $1; subs += $2; loc += $1 - $2 } END { printf "added lines: %s, removed lines: %s, total lines: %s\n", add, subs, loc }'

统计23个周内所有代码行数按开发者：
git log --format='%aN' | sort -u | while read name; do echo -en "$name\t"; git log --since="23 weeks ago" --author="$name" --pretty=tformat: --numstat | awk '{ add += $1; subs += $2; loc += $1 - $2; all+= $1 + $2 } END { printf "added lines: %s, removed lines: %s, total lines: %s, all change lines: %s \n", add, subs, loc, all }' -; done
