Git常用统计命令

1. 按照增删代码行数，输出百分比，对贡献者进行排名

git log --all --no-merges --numstat --pretty=format:"%an" | awk '
    /^[^0-9-]/ {user=$0}
    /^[0-9]/ {add[user]+=$1; del[user]+=$2; total+=$1+$2}
    END {
        for (u in add)
            printf "%s: %d/%d = %.2f%%\n", u, add[u]+del[u], total, (add[u]+del[u])*100/total
    }' | sort -t= -k2 -nr
