How to launch cmd running a command from powershell

Question

I want to write a powershell script that sets up a development environment. Firstly, I want to launch two command prompts which are running yarn run dev:client and yarn run dev:server respectively.

I have tried start cmd and Start-Process cmd -Argument yarn,run,dev:server, but am unable to get the newly launched command prompt to run the command.

How do I do this?

CMD /K "<INSERT_COMMAND_HERE>" so ie. Start-Process cmd -ArgumentList '/K "echo Hi!"' — Jonas

What does "unable to get the newly launched command prompt to run the command" mean? The cmd.exe window opens but the command doesn't run? The cmd.exe window doesn't open? — Bill_Stewart

The generic way is: cmd /c "insert_your_command_here"

This means in your case you would execute:

cmd /c "yarn run dev:client"
cmd /c "yarn run dev:server"

What about:

$arg="run dev:server"
Start-Process -FilePath path_to_yarn  -Args $arg -passthru -RedirectStandardError err.log
