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

I am running a program which calls powershell via the system command multiple times. At the end I end up with many opened windows. I would like either these windows to close after each iteration has been completed or run in the background without opening the command window.
pubPath = 'powershell -inputformat none cd C:some path in my pc &';
[status,publisher] = system(pubPath);
I've tried the exit and exit() commands at the end of my paths but nothing has worked so far. Any help would be great.
For future reference, I found a solution to my issue. Execute this command after the loop executes all its instances and all the spawned command windows will be closed. BECAREFUL, you might kill more processes than you want.
system('taskkill /IM cmd.exe')
When using the CMD prompt, you can "type ahead" commands and when the current operation is finished, the command will be issued to the CMD prompt.
When you execute the following in CMD, foo will run, then bar will run. However in PowerShell, it will ignore bar.exe<ENTER> because foo is running. Is there a way around this? It's pretty frustrating to have to wait for a command to finish before executing a subsequent command.
foo.exe<ENTER> (takes 60 secs)
bar.exe<ENTER>
It depends on the host. In the console host (powershell.exe) it works the same as cmd (the way you want it to). In ISE (powershell_ise.exe) it does not.
You won't be able to change this behavior.
Your workaround then is to use the console host instead of ISE for interactively typing commands.
If you know you're going to run both, write foo.exe; bar.exe
Or write them both in the ISE edit window, and press F5 to run.
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 got some strange behaviour when executing a powershell script.
When I run my script using the ISE it works just fine.
When I open Powershell.exe and run my script it works just fine.
When I open cmd, and start my script using powershell.exe -noexit
./myscript.ps1, myscript works just fine.
When I double-click myscript however, powershell opens for some milliseconds, I see that it shows some error (red font) and the powershell window closes. I'm unable to track down the error causing this problem since the powershell windows closes to fast.
I even tried one single big try-catch block around my hole script, catching any [Exception] and writing it down to a log file. However: the log file is not generated (catch is not called).
How can I track that issue? What could possibly be causing the trouble?
Please note that my execution-policy is set to unrestricted.
Before trying the suggestion invoke this to see your current settings (if you want restore them later):
cmd /c FType Microsoft.PowerShellScript.1
Then invoke this (note that you will change how your scripts are invoked "from explorer" by this):
cmd /c #"
FType Microsoft.PowerShellScript.1=$PSHOME\powershell.exe -NoExit . "'%1'" %*
"#
Then double-click the script, it should not exit, -NoExit does the trick. See your error messages and solve the problems.
But now all your scripts invoked "from explorer" keep their console opened. You may then
remove -NoExit from the above command and run it again or restore your
original settings.
Some details and one good way to invoke scripts in PS v2 is here.
Unfortunately it is broken in PS v3 - submitted issue.
by default, for security reason when you double clic on a .ps1 file the action is : Edit file, not Run file .
to execute your script : right-click on it and choose run with powershell
I also wasn’t able to run a script by double clicking it although running it manually worked without a problem. I have found out that the problem was in the path. When I ran a script from a path that contained spaces, such as:
C:\Users\john doe\Documents\Sample.ps1
The scipt failed to run. Moving the script to:
C:\Scripts\Sample.ps1
Which has no spaces, solved the problem.
This is most likely an issue with your local Execution Policy.
By default, Powershell is configured to NOT run scripts that are unsigned (even local ones). If you've not signed your scripts, then changing your default double-click 'action' in Windows will have no effect - Powershell will open, read the execution policy, check the script's signature, and finding none, will abort with an error.
In Powershell:
Help about_execution_policies
gives you all the gory details, as well as ways to allow unsigned scripts to run (within reason - you'd probably not want to run remote ones, only ones you've saved onto the system).
EDIT: I see at the tail end of your question that you've set Execution Policy to 'unrestricted' which SHOULD allow the script to run. However, this might be useful info for others running into execution policy issues.
If you would catch the error you will most likely see this
The file cannot be loaded. The file is not
digitally signed. The script will not execute on the system. Please
see "Get-Help about_signing" for more details.
Because you are able to run it from the shell you started yourself, and not with the right mouse button click "Run With PowerShell", I bet you have x64 system. Manually you are starting the one version of PowerShell where execution policy is configured, while with the right click the other version of the PowerShell is started.
Try to start both version x64 and x86 version and check for security policies in each
Get-ExecutionPolicy
I was in exactly the same situation as described in the question : my script worked everywhere except when double-clicking.* When I double-clicked a powershell windows would open but then it will close after a second or so. My execution-policy is also set to unrestricted.
I tried the selected answer concerning FType Microsoft.PowerShellScript.1 but it didn't change anything.
The only solution I found was a work around: create a bat file which start the powershell.
Create a file, copy this and modify the path : powershell.exe -File "C:\Users\user\script\myscript.ps1"
Save it as a .bat
Double-click the bat
I also used .ahk to start my powershell with a shorcut and it didn't work when pointing directly to the powershell. I had to point to the .bat
#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
