Example #4

To save user name in the file “user.txt” use:

C:\>net config | find “User name” > user.txt
or
C:\>net config | find “User name” > %temp%.\user.txt

Example #5

Finally a little bit more sophisticated script for advanced users (save this code in getuser.bat file):

@echo off
SET user=
if not ‘%1==’ goto 2nd
net config workstation | find “User name” > %temp%.\getuser.bat
%temp%.\getuser.bat

:2nd pass
set user=%2
if “%user%”==”" ECHO No User name set
if not “%user%”==”" ECHO User=%user%
del %temp%.\getuser.bat

Then execute above script:

C:\>user.bat

User=kris
