Batch File – How to Check the Exit Code of the Last Command in Batch File

batchwindows xp

Inside a batch file on Windows, I use 7-zip like this:

...\right_path\7z a output_file_name.zip file_to_be_compressed

How could I check the exit code of 7z and take the appropriate action ?

Test for a return code greater than or equal to 1:

if ERRORLEVEL 1 echo Error

if %ERRORLEVEL% GEQ 1 echo Error

or test for a return code equal to 0:

if %ERRORLEVEL% EQU 0 echo OK

You can use other commands such as GOTO where I show echo.

Exit batch file from subroutine

Add this to the top of your batch file:

@ECHO OFF
SETLOCAL

IF "%selfWrapped%"=="" (
  REM this is necessary so that we can use "exit" to terminate the batch file,
  REM and all subroutines, but not the original cmd.exe
  SET selfWrapped=true
  %ComSpec% /s /c ""%~0" %*"
  GOTO :EOF
)

Then you can simply call:

EXIT [errorLevel] if you want to exit the entire file
EXIT /B [errorLevel] to exit the current subroutine
GOTO :EOF to exit the current subroutine

Windows – Batch file process leaves extra command prompt open

You could use CALL and add the /MIN switch with the START command to keep it more hidden and ensure the CMD window disappears when running per the way you have the logic setup in your above example.

I made some quick adjustments and added this logic for you to have an exact example of what I used and confirmed works as you explain you need it to work.

Example Script

@echo off

CD /D C:\Users\%username%\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup

echo @echo off > startup.bat
echo START /MIN "" "https://google.com">> startup.bat
echo EXIT /B>> startup.bat

CALL startup.bat
EXIT /B
