PowerShell command does not die

[Sauraus]

NOTE: Not sure if this is a childprocess issue or Powershell.

The following Powershell command will echo and then exit if executed in a CMD shell, however if the same is invoked through childprocess this doesn't happen.

PS> echo hello; exit $LASTEXITCODE

Please include the code you're using to run PowerShell and CMD through ChildProcess.

Can you reproduce the problem without the Vagrant wrapper? What do you mean by "does not die" - do you see powershell.exe in the machine's process list?

ChildProcess is not executing the command in a shell, it is executing powershell.exe directly through the CreateProcess system call. You're passing [";", "exit", "$LASTEXITCODE"] as arguments to powershell.exe. Is that the intention?

I don't have a windows machine to try this on at the moment, but if you want anything interpreted as in cmd.exe, you'll have to invoke the interpreter yourself, e.g. something like:

process = ChildProcess.build("cmd.exe", "/c", "powershell Expand-Archive ...")
process.start

Correct powershell.exe remains running as a child process long after the Expand-Archive has finished, which I can see in process explorer.

I tried the ;exit $LASTEXITCODE for force the powershell.exe process to terminate after running the command Expand-Archive.

PowerShell has the equivalent of cmd.exe /c being PowerShell.exe -Command but even if I use that something in the way how ChildProcess spawns powershell keeps it from exiting when done.

I very much doubt the problem is ChildProcess. Have you tried passing the -NonInteractive flag to PowerShell (from http://technet.microsoft.com/en-us/library/hh847736.aspx)?

[jarib]

Also, your gist does not use -Command flag. You should try that:

ChildProcess.build("PowerShell.exe", "-Command", "the full command in a string")

Going to close this since there's no response in a month.
