I have a windows batch file that looks similar to:
C:\DoStuff.cmd
move output.bak C:\newfolder\output.bak
The problem i have is that DoStuff.cmd executes a java program that once complete exits the batch run back to the command prompt. Line 2 never gets hit.
i have tried the following instead to execute the command in a new window:
start "My program" /WAIT C:\DoStuff.cmd
move output.bak C:\newfolder\output.bak
What happens with the above is that the new command window spawns the cmd file runs and exits back to a waiting command prompt and the window never closes, leaving the first command window waiting and the second doing nothing stuck after finishing step one.
How do i execute the first command without it having control of the batch run somehow?
many thanks in advance
You can use DOS call command:
#echo off
call C:\DoStuff.cmd
echo Exit Code = %ERRORLEVEL%
After getting error code you can proceed for example with:
if "%ERRORLEVEL%" == "1" exit /B 1

In Windows PowerShell 5.1, after run & code ., a VSCode window opens, and the control returns back to PowerShell immediately. After the PowerShell exists, the VSCode will not be terminated.
On the other hand, when invoke other external program, such as WinMerge, after run & WinMergeU, a WinMerge window opens, and the control does not return back to PowerShell until WinMerge window is closed. And If PowerShell exists, WinMerge will be terminated.
Why the behaviour is different?
the difference is what is actuall happening:
when you run the command code, you are not really running code.exe. its starting a cmd script that spawns a new code.exe process with whatever arguments you passed it.
to see what a command actually executes, use the command get-command 'yourcommand', or with code get-command code.
this will show the follwing source: C:\Users\{username}\AppData\Local\Programs\Microsoft VS Code\bin\code.cmd.
Opening up this will show you:
#echo off
setlocal
set VSCODE_DEV=
set ELECTRON_RUN_AS_NODE=1
"%~dp0..\Code.exe" "%~dp0..\resources\app\out\cli.js" --ms-enable-electron-run-as-node %*
endlocal
so this means that in both cases you are waiting for execution to end, but for code its a code.cmd script and not actually code.exe.
If you want to start new processes and don't wait for them, you can use the command start-process winmergeu
How can I terminate a terminal/PowerShell window from a .ps1 script? I would like it to work the way exit in command line works, but when I put that in a PowerShell script it only terminates the script.
Environment.Exit() will terminate the whole process:
# replace 0 with a non-0 error code if you want to indicate some sort of failure
[Environment]::Exit(0)
I have to run cmd / c from a program, run the start command xx.exe, and I capture the result (there xx.exe?). until everything is right, however, remains open the console with the error popup. how can I close the console with the error?
Usually win32 applications will close the command prompt after execution. If this isn't the case with what you're trying to run, you could:
Run it from Windows "Run" option (Windows button+R) than your program name and path in prompt.
Run it from a batch file, like so:
runMe.bat:
START "" "C:\windows\notepad.exe"
EXIT`
Than just run runMe.bat from wherever. Notice the 'exit' command that closes the command prompt after execution.
Read more about batch files, the start command, and this issue here, and there.
Good luck!
I'm studying the code of Mobile Terminal which is a command line for iPhone.
The projects emulates a VT100 terminal.
I can monitor everything that goes through the terminal (ascii and control characters)
but I can't figure out how the terminal knows that a command completed its output. How
does the terminal know when to display the prompt again ? Is there a special control
character that every command sends when ending ?
To me it sounds like you're running a shell in the terminal, because a VT100 doesn't show a prompt (AFAIK).
A shell creates a child process and executes the command there. The shell then simply waits until this child process is finished and then prints its prompt again.
An exception is when the command is run in the background (some_command &), the shell doesn't wait for the child to exit and immediately prints the prompt again.
#echo off
start /wait notepad
start worpad
This is the code i have written in a batch file. My aim is to stop the batch file execution till the notepad application gets closed. Its working perfect but the thing is, Its displaying the command prompt also .Its opening the command prompt when i execute
start /wait notepad in my batch file.
The command prompt gets closed when i close my notepad. But i dont want the command prompt.How do i make that. I even tried these
cmd /c start /wait notepad
even the above command is not working. How do i make it.How do i open only notepad without the command prompt and wait till it is closed ?
As I said in my answer to one of your previous questions, the command prompt window is there because it is the tool that processes the batch file. The command prompt window is the working window of the CMD.EXE program, just like Notepad's working window is the one where you are editing text files. Typically, running a program with its working window hidden is a non-trivial task, unless the program has a pre-defined mode of running with the hidden window. As it happens, CMD does not have such a mode.
However, there is a way of starting a program with its window minimised. You only need to create a shortcut to your program (it can be a batch file too), then open the shortcut's properties, and on the Shortcut tab, set the Run property to Minimized. To make it clearer, here's an illustration:
Or maybe you can just use the
ping localhost -n ( your time in second ) >nul
So your code will be like this
#echo off
start notepad
ping localhost -n ( your time in second ) >nul
start worpad
