Ping命令返回碼ERRORLEVEL問題

feny

1，在CMD窗口下，直接運行命令ping 192.168.0.1  然後用ECHO %ERRORLEVEL%查看，如果ping通，返回碼為0；ping不同，返回碼為1;

  2, 但是放在*.BAT文件中直接運行，不管通不通，返回碼都是0。

請教大蝦，爲什麽

我怎么没有出现这个现象？

1. @echo off
   
2. ::我的网关是192.168.1.1
   
3. ::下面是成功的：
   
4. ping 192.168.1.1
   
5. echo %errorlevel%
   
6. ::下面是失败的：
   
7. ping 192.168.2.1
   
8. echo %errorlevel%
   
9. pause

复制代码

结果是：
