Windows initializeCommand not using default shell

[martinbiard]

What happened?

On Windows, when using an initializeCommand, it always tries to execute by running it through sh -c ....

I wanted to use a common technique to invoke a script in a cross platform compatible way i.e. you name your scripts as follows:

myscript
myscript.cmd
myscript.ps1

Then, in devcontainer.json, you set your initializeCommand simply to myscript such that on linux shells it will execute myscript and on Windows it will execute myscript.cmd from which you can then pass onto myscript.ps1.

What did you expect to happen instead?

I expected the initializeCommand to be invoked through the OS default shell.

How can we reproduce the bug? (as minimally and precisely as possible)

My devcontainer.json:
This is the default config from microsoft/vscode-remote-try-node with only added initializeCommand at the end.

  "initializeCommand": "initializeCommand" // also tested with ["initializeCommand"] array format
}

DevPod Provider:

• Local/remote provider: docker

Anything else we need to know?

The only little workaround I have for now is adding C:\Program Files\Git\bin to my PATH to make sh.exe available, but Git does not add this directory to the PATH by default on Windows (it adds C:\Program Files\Git\cmd which doesn't contain sh.exe). Also, this workaround is not great because what I really want is access to powershell.

From the devcontainer documentation, you would expect that by saying clearly that it runs the initializeCommand on the host, that it would use the host's native shell. Then, if you really rather use some sh.exe, you can just call it from the native shell.

Hey @martinbiard, thanks for opening the issue. Seems like you've hit a blind spot of DevPod, we'll fix that
