PowerShell script to open a new PowerShell window and run command

Question

I'm looking for a way to write a script which is able to open a new PowerShell window and to run command. E.g. I'd like to launch PowerShell, in this window I need to run a script able to open a new PowerShell window inside which the command pwd is executed.

Use the Start-Process cmdlet - on Windows, it runs the specified executable in a new window by default (on Unix, the command invariably runs in the same window). — mklement0

Hello @mklement0 I tried to run the command Start-Process powershell.exe pwd, but the new PowerShell screen appears and disappears quickly. What did I do wrong? — Gennaro Arguzzi

This does the job, you forgot -NoExit Start-Process powershell -ArgumentList '-NoExit "& {pwd}"' Don't forget to check help powershell /?, Get-Help Start-Process — andr3yk

Plus 1 for the need for -noexit to keep the new window open (only needed if -Command / -c are also specified), but two asides:

While passing arguments as an array to -ArgumentList conceptually the best approach, it is unfortunately ill-advised due to a long-standing bug in Start-Process, still present as of this writing (v7.1) - see GitHub issue #5576. For now, using a single string comprising all arguments, enclosed in embedded "..." quoting as necessary, is the only robust approach. As discussed in the linked GitHub issue, an -ArgumentArray parameter that supports robust array-based argument passing may be introduced in the future.

Note that there's no reason to use & { ... } in order to invoke code passed to PowerShell's CLI via the -command (-c) parameter - just use ... directly. Older versions of the CLI documentation erroneously suggested that & { ... } is required, but this has since been corrected.

*Correction to the first comment: -noexit is only needed if one of the following parameters are also specified: -Command (-c), -EncodeCommand, -File.
