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.
:: 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 error level to 5
Exit /B 5
To make this more flexible you can change the subroutine to set any errorlevel like this:
Exit /B %1
Now you can call the subroutine: call :setError 6 replacing 6 with whatever value you need the errorlevel to be set to.
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
VERIFY - Provides an alternative method of raising an errorlevel without exiting
KILL - Remove a program from memory
Powershell: Exit - Exit Powershell
Equivalent bash command (Linux): break - Exit from a loop
