![]() Is like a tube to the surface that I can breathe through. Doing this way, the process running the command will never ends and you will always get STILLACTIVE when querying GetExitCodeProcess () (meaning the process is still running). I’m underwater most of the time, and music You are passing option /k to cmd.exe, meaning you want the shell to remain active after executing command dir. “Making music is not about a place you go. ![]() Using EXIT /b to exit a nested FOR loop (so skipping the values X,Y andZ), but still continuing the main loop: Off This will only work if the inner FOR loop is contained in a separate subroutine, EXIT /b terminates the subroutine.Įcho If we get this far the file was found For example the following commands would all set ERRORLEVEL to 0 within your batch-file: VERIFY > nul cmd. Either that or use a command that resets the errorlevel for you, such as echo, findstr etc. Where the number 0 is your wanted errorlevel. 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, if EXIT /b can be used to exit a FOR loop that is nested within another FOR loop. in another batch file and call it from your primary script. Performance if the loop is (pointlessly) counting up to a large number. Itself continues until the end count is reached. The execution of the commands in the loop is stopped, but the loop You should never attempt to directly write to the %ERRORLEVEL% variable, (SET errorlevel.) instead use the EXIT command as a safe way to alter the value of the internal ERRORLEVEL pseudo variable. ErrorlevelsĮXIT /b has the option to set a specific errorlevel, 0 for sucess, 1 or greater for an error.ĮXIT without an ExitCode acts the same as goto:eof and will not alter the %ERRORLEVEL% To close an interactive command prompt, the keyboard shortcut ALT + F4 is an alternative to typing EXIT. If quitting CMD.EXE, set the process exit code no. To be more explicit about what others have said: Don't think too hard about it. It's not portable, though, the only portable exit values are 0, EXITSUCCESS and EXITFAILURE. Only the script (or subroutine) but not CMD.EXEĮxitCode Sets the %ERRORLEVEL% to a numeric number. 42 is clearly the opposite of a named value - it's a magic value that only the author of the code knows why it's there. B When used in a batch script, this option will exit ![]() The command processor (CMD.EXE) optionally setting an errorlevel code. The function starts a new cmd/shell process, executes command, exits the process, and returns to the MATLAB process. Quit the current batch script, quit the current subroutine or quit
