批处理文件中的比较结果不正确

2

这批：

@echo off
set _ping_cmd=ping -n 1 192.168.1.1

FOR /L %%G IN (1,1,60) DO (

    FOR /f "tokens=4 delims=(=" %%G IN ('%_ping_cmd% ^|find "loss"') DO (
        echo Result is [%%G]
        IF  %%G == " 0 " GOTO ON
    )
    timeout 60
)

:ON

产生了这个输出：

D:\>live

Result is [ 0 ]

Waiting for 52 seconds, press a key to continue ...

为什么？显然，%%GIS " 0 "，但goto没有执行..

您正在为两个FOR调用重用相同的变量名称。这是在惹麻烦。
