From time to time you may wish to find out who is logged into a machine. I find this batch file handy for doing this. Its quick, simple and easy.

Just copy and paste the below code into notepad and save the file as who.bat

@echo off

:CHECK
echo Checking Connection ...
ping %1 -n 1  | findstr "TTL=" >nul && GOTO MAIN || GOTO ERROR
GOTO END

:ERROR
echo Device Unreachable
GOTO END

:MAIN

wmic /node: "%1" computersystem get username

GOTO END

:END

echo.

Now open the command prompt. run to the location of the script then a space then the name of the machine. For example

C:\who.bat Computer1

All Done!
