@echo off
set /p ip=Enter IP address
for /f "tokens=1,2 delims= " %%i in (test.txt) do (
if %ip%==%%i (echo %ip% %%j)

test.txt
192.168.0.4 00-1C-F1-00-65-7F
192.168.0.238 00-1C-F1-00-68-84
192.168.0.42 00-1C-F1-00-69-54
192.168.0.41 00-1C-F1-00-97-80
192.168.0.22 00-1C-F1-00-68-80

If the entered IP matches an IP in test, then display the corresponding IP and MAC. If it doesn't match, then continue to the next step...... How should this be written??

Continue to the next step??? What do you mean? Which step??

Does the OP mean: find the line in test.txt that has the same IP as the entered one??

Or??

Enter an IP
If the entered IP exists in test, then display "IP exists". If the entered IP is not in test, then display "IP is incorrect, re-enter it"

Based on the entered IP and MAC... change the corresponding IP and MAC.... What I mean is, if I enter 192.168.0.4 00-1C-F1-00-67-8E, and if the IP 192.168.0.4 exists in test, then replace the 192.168.0.4 00-1C-F1-00-65-7F in test with 192.168.0.4 00-1C-F1-00-67-8E

Problem solved... thanks... but there's one part of the code in post #7 that I don't understand??
if "%var1%"=="%%c" (echo %var%>>_test.txt) else echo %%c %%d>>_test.txt
Doesn't else here mean that echo %%c %%d>>_test.txt is executed only when if "%var1%"=="%%c" (echo %var%>>_test.txt) is not true??
