VERIFY - Provides an alternative method of raising an error level without exiting.Įquivalent PowerShell: Exit - Exit PowerShell or break - Exit a program loop.Įquivalent bash command (Linux): break - Exit from a loop.Windows 8 order dialog box appears randomly, causing all open windows close If I didn’t have the music I’d be under water, dead” ~ Fiona Apple I’m underwater most of the time, and music is like a tube to the surface that I can breathe through. “Making music is not about a place you go. If Command Extensions are disabled, the EXIT command will still work but may output a spurious 'cannot find the batch label' error. Use EXIT /b to exit a nested FOR loop (so skipping the values X,Y and Z), but still continue back to the main outer loop: Off This will only work if the inner FOR loop is contained in a separate subroutine, so that EXIT /b (or goto:eof) will terminate the subroutine.Įcho If we get this far the file was found In the case of an infinite loop, this EXIT /b behaviour will cause the script to hang until manually terminated with Ctrl + CĮxiting nested FOR loops, EXIT /b can be used to exit a FOR loop that is nested within another FOR loop. This will cause slow performance if the loop is (pointlessly) counting up to a large number.
When EXIT /b used with FOR /L, the execution of the commands in the loop is stopped, but the loop itself continues until the end count is reached. The script will then act as though Ctrl-C had been pressed. To use this in a batch file, launch a new CMD session and immediately exit it, passing this errorlevel. Ctrl-CĪn errorlevel of -1073741510 will be interpreted by CMD.exe as a Ctrl-C Key sequence to cancel the current operation, not the entire script which EXIT will do. You should never attempt to directly write to the %ERRORLEVEL% variable, ( SET ERRORLEVEL n ) instead use EXIT /b n as a safe way to set the internal ERRORLEVEL pseudo variable to n.

The exit code can be an integer of up to 10 digits in length (positive or negative).ĮXIT without an ExitCode acts the same as goto:eof and will not alter the ERRORLEVEL ErrorlevelĮXIT /b has the option to set a specific exit code, EXIT /b 0 for sucess, EXIT /b 1 (or greater) for an error.
If you start a second nested CMD shell (or PowerShell), this will be added to the TITLE of the CMD/terminal window, when you EXIT back to the initial shell, the Title will also revert making it possible to track how many nested shells you have open. To close an interactive command prompt, the keyboard shortcut ALT + F4 is an alternative to typing EXIT. If quitting CMD.EXE, sets the process exit code no. If executed on the command-line it will close CMD.exeĮxitCode Sets the %ERRORLEVEL% to a numeric number. Only the script (or subroutine) but not CMD.EXE B When used in a batch script, this option will exit Close the current batch script, exit the current subroutine or close the CMD.EXE session, optionally setting an errorlevel.
