Feature: Add an option to bypass shell wrapper

[r-darwish]

Issue Description

Due to gsudo's shell detection, trying to run a command with the Windows Powershell from Powershell Core will cause gsudo to run Powershell Core first. It would be useful if we can have a flag to disable the shell detection.

Steps to Reproduce

Run the following command from Powershell core:

gsudo --debug "C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\powershell.EXE" "-NoProfile" "-Command" 'echo $PSVersiontable.psversion'

Screenshots

Context:

• Windows version: 20H2
• gsudo version: 0.7.3

Hi! Thanks for your really accurate bug report.

The shell detection is adding an extra 'powershell core' process, and the indirection makes it a quotation hell syntax.

Let me give you a shamefull workaround. Try:

cmd /c gsudo --debug '"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" -Command "Echo $PSVersionTable.PSVersion"'

or without the cmd, you need to escape the $ sign.

gsudo --debug `"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe`" -Command '"echo `$PSVersionTable.PSVersion"' 

or an example with variable substitutions:

$command='Echo $PSVersionTable.PSVersion'
gsudo --debug "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" -Command `"($Command.Replace("$","``$"))`"

It would be useful if we can have a flag to disable the shell detection.

I agree. It would imply that the command to run be something that can be executed by CreateProcess such as an .EXE, .CMD, .BAT or .COM. Shell statements of course won't be supported (e.g. md on cmd, CmdLets on PS).

I'm unsure on how to name the 'feature', or what letter to assign to it (as in -x). Suggestions accepted.

Hi @gerardog, thanks for the workaround. I applied it here and it seems to work. Since this is a pretty niche feature that I'm asking, I think it's okay that it will only have a full named flag, such as --no-shell

Hi @r-darwish, this will be released in v1.0. An early draft pre-release is open for testing in case you want to try it.
(please don't ship it into topgrade until released)

Released in v1.0.0 (PR #94)
