一键重置git分支脚本

由于公司的上线封版机制，每个上线窗口结束之后，需要将qa和develop分支切换成上个窗口的beta灰度分支，虽然逻辑很简单，但是处理起来还有有点小繁琐，所以写了一个脚本干这个事，其实就是将用到的git命令打包，叫脚本去执行了自己本该执行的git命令，简单记录一下

#!/usr/bin/env bash
if [ $# -le 3 ]
  then
    echo "参数有误({源分支},{重置分支},{本地项目根目录},{项目名称(api/www)}) 举例："
	echo "8.29.1.0 qa D:/wangxt-git api"
    exit
fi
if [ -z $2 ]
  then
    LIST=(qa,develop)
  else
    LIST=($2)
fi
if [ -z $3 ]
  then
    WORK_PATH=D:/wangxt-git
  else
    WORK_PATH=$3
fi
if [ "api" = $4 ]
  then
    P_NAME=/api
	F_NAME=/framework
  else
    P_NAME=/www
	F_NAME=/framework
fi
