关闭打印
echo off
当前行不打印
@
常常看到bat文件开头就是 @ echo off
变量设置变量
set a=5
取变量
%a%%号转义
%% 例如SQL like '%name%' 在bat里写为 like '%%name%%'函数
:funcname //函数名称 %1 //取第一个参数 %2 //取第二个参数 //写你的代码 @ goto:eof //函数结束固定写法
函数调用
call ::funcname //传参 call ::funcname param1 param2跳转
:start echo start :middle echo middle :user echo user :end
代码按顺序执行，但是可以使用goto :标记 跳转,不执行跳过的代码
:start echo start goto user //middle将被跳过，直接执行:user以及:user后面的 :middle echo middle :user echo user :end查询进程号并杀掉
