批处理小技巧-输入序号运行指定程序

还是以微信为例，当然可以随意自由替换里面的程序代码。

@echo off&color 2f
  
:ch
 cls
 echo 请选择：
 echo.echo =============================
 echo  1 运行一个微信
 echo  2 运行五个微信
 echo  3 退出
 echo =============================
 echo  如果选择有误将返回重选
 set/p aa=请选择序号后回车:
  echo.%aa%|findstr "^[1-3]$">nul&&goto M%aa%
 goto ch
  
:M1
start "" "C:\Program Files (x86)\Tencent\WeChat\WeChat.exe"
exit
 goto ch

  
:M2
start "" "C:\Program Files (x86)\Tencent\WeChat\WeChat.exe"
start "" "C:\Program Files (x86)\Tencent\WeChat\WeChat.exe"
start "" "C:\Program Files (x86)\Tencent\WeChat\WeChat.exe"
start "" "C:\Program Files (x86)\Tencent\WeChat\WeChat.exe"
start "" "C:\Program Files (x86)\Tencent\WeChat\WeChat.exe"
exit
 goto ch

:M3
 exit
