git统计代码量

记录一下
这个脚本应用场景是读取某个文件夹下所有git仓库的log，然后根据author 和 开始结束日期计算代码量（已在MacOS13.0验证）

#!/bin/bash
# author: zhangsan
# desc: 统计代码量

repository="/Users/xxx/Desktop/workspace/Apple/Migu_lib"

# 定义ANSI转义码
RED='\033[0;31m'
GREEN='\033[0;32m'
YELLOW='\033[0;33m'
CYAN='\033[0;36m'
NC='\033[0m' # 重置颜色

author="zhangsan"
