windows - 从 ping 中提取 IP 到 bat 脚本中的变量中

Question

无论如何我可以做到这一点吗？

@echo off
REM #Testing FIND in IPCONFIG

setlocal EnableDelayedExpansion

for /f "tokens=3" %%a in ('ping localhost ^| findstr /i "reply"') do (
  set address=%%a
  set address=!address::=!
)

ipconfig /all | findstr %address%
if ERRORLEVEL = 1 goto VIP_NOT_FOUND

REM #We are here becuase the find returned a result.
REM #It is safe to execute the rest of the application.
REM #EXECUTES THE SCRIPT HERE

echo "testing works" >> testing.txt

:VIP_NOT_FOUND
REM #This part of the script is where you would handle any
REM #error logging or other admin related
echo "Could not find a VIP. - Exiting"
echo "end of script reached."

我在 windows server 2k8 ENG 版本上运行这个脚本。它似乎一直在给我 findstr : bad command line。但我不确定问题出在哪里。

像这样的东西应该工作：

@echo off

setlocal EnableDelayedExpansion

for /f "tokens=3" %%a in ('ping myhost.com ^| find /i "reply"') do (
  set address=%%a
  set address=!address:~0,-1!
)

ipconfig /all | findstr "%address%" >nul && (
  rem Do stuff
)

如果主机具有 IPv4 和 IPv6 地址，并且您正在寻找 IPv4 地址，请使用ping -4而不是仅使用ping.
