Issue: cmd those params have spaces failed when executed by gsudo

[mekrina]

in powershell 7.5.1 and the latest gsudo 2.6.0, cmd those params have spaces failed when executed by gsudo
for example:
ls "C:\Program Files" just work fine, but
gsudo ls "C:\Program Files", there is an error:
Get-ChildItem: Cannot find path 'C:\Program' because it does not exist.
the program split the quoted path to two part
the same problem occured when using mv, cp...

however, I test the powershell 5.1 and cmd, there are no problems;
I don't kown if it's a bug of powershell7.5.1 or gsudo, I decided to post a issue here

Context:

• Windows version: Win11 24H2
• gsudo version: 2.6.0

Can confirm the same, this is quite literally breaking behavior, making tool unusable atm.

I've been debugging this for a bit and here are two examples:

1. It's because gsudo launches cmd like this:

(This example is not the same as from this ticket, i'm launching gsudo from node.js code so it uses cmd as invoking shell)

gsudo --debug my-command "C:\some path" --someOtherFlag "C:\some other path"
...
Debug: Creating target process: C:\WINDOWS\system32\cmd.exe /s /c "my-command \"C:\some path\" --someOtherFlag \"C:\some other path\""

And this quotation it this case is incorrect, if i run this directly without gsudo (just cmd /s /c... it doesn't work either, if i use just "" instead of escaped \" it works.

2. And i've tried example from @mekrina and it seems to be the same case with pwsh7 as invoking shell:

❯ gsudo --debug ls "a b"
...
Debug: Creating target process: "C:\Program Files\PowerShell\7\pwsh.exe" -NoLogo -NoProfile -Command "ls "a b""
...
Get-ChildItem: Cannot find path 'D:\dev\src\a' because it does not exist.

Calling pwsh directly with the same params:

❯ pwsh -NoLogo -NoProfile -Command "ls "a b""
Get-ChildItem: Cannot find path 'D:\dev\src\a' because it does not exist.

Calling with double double quotes (""):

❯ pwsh -NoLogo -NoProfile -Command "ls ""a b"""

    Directory: D:\dev\src\a b
