goto :eof


if not "!%~2!" == "" set %~2=%%i以上代码看不懂，上面没有用延迟变量，为什么%~2要加！呢？另外%~2又是什么意思呢？请指教。

%~2 是表示把 “ip"的引号删除。。

至于为什么要加!
我也不明白。

%~2代表把引号删除是什么原理呢????

call :select "ip address" "ip"
call :select "Physical Address" "mac"
call :select "Default Gateway""gateway"
call :select "DNS Servers" "dns"
call :select "Description" "netcard"

......

:select
for /f "tokens=2 delims=:" %%i in ('ipconfig /all ^| findstr /i /c:%1') do if not "!%~2!" == "" set %~2=%%i
......

%~1为红色
%~2为绿色
