Quit the current batch script, quit the current subroutine or quit the command processor (CMD.EXE) optionally setting an errorlevel code.
Syntax EXIT [/B] [exitCode] Key /B When used in a batch script, this option will exit only the script (or subroutine) but not CMD.EXE exitCode Sets the %ERRORLEVEL% to a numeric number. If quitting CMD.EXE, set the process exit code no.
You should never attempt to directly write to the %errorlevel% variable, (i.e. don’t try anything like SET errorlevel...) using the EXIT command provides a safe way to alter the value of the built-in errorlevel variable. Unlike goto:eof the Exit /b command allows you to set a specific errorlevel.
Exiting nested FOR loops, if EXIT /b can be used to exit a FOR loop that is nested within another FOR loop.
This will only work if the inner FOR loop is contained in a separate subroutine, EXIT /b terminates the subroutine.
Exit if a required file is missing
If not exist MyimportantFile.txt Exit /b
Echo If we get this far the file was found
Set the errorlevel to 5
Exit /B 5
Using Exit /b to exit a nested FOR loop (so skipping the values X,Y andZ), but still continuing the main loop:
@Echo Off Setlocal For %%A in (alpha beta gamma) DO ( Echo Outer loop %%A call :inner ) goto :eof :inner For %%B in (U V W X Y Z) DO ( if %%B==X ( exit /b 2 ) echo Inner loop Outer=%%A Inner=%%B )
EXIT is an internal command.
“Making music is not about a place you go. It’s about a place you get out of. I’m underwater most of the time, and music is like a tube to the surface that I can breathe through. It’s my air hole up to the world. If I didn’t have the music I’d be under water, dead” ~ Fiona Apple
