Get Errorcode of Reg Query in one Line

2
votes

i want to get either 0 or 1 from the following reg query: reg query "hklm\Software\Microsoft\Windows\Currentversion\WindowsUpdate\Auto Update\Rebootrequired"

Instead of getting the Updates or the Error Message, i want to output the Errorcode.

The Problem is, that the whole command must be put in one Line!

Something like "reg query.... 2>&1 | echo %Errorlevel%

Thanks!

Sorry for my bad English!

If you need to do it all on one line then you will need to force delayed expansion to be enabled so that you can echo the errorlevel correctly.

cmd /V:on /C "reg query "hklm\Software\Microsoft\Windows\Currentversion\WindowsUpdate\Auto Update\Rebootrequired" >nul 2>&1 &echo !errorlevel!"

You can also use this.

reg query "hklm\Software\Microsoft\Windows\Currentversion\WindowsUpdate\Auto Update\Rebootrequired" >nul 2>&1 &CALL echo %^errorlevel%
