Call for Windows testers (CYGWIN, MSYS, MINGW, WSL)

[dylanaraps]

Edit: Those using CYGWIN, MSYS or MINGW, test out #22

Send me the full outputs of the following commands:

• wmic os get Caption (needed for OS name).
  • Does wmic have an option to exclude Caption from the output?
• wmic computersystem get manufacturer,model (needed for host information).

Notes:

• WSL detection is possible through checking /proc/version and uname -r.
• Uptime (in seconds) is accessible through /proc/uptime.
• Memory is accessible through /proc/meminfo.

This is on stock Windows.

wmic os get Caption:

Caption
Microsoft Windows 10 Home

note: I have no clue how to use wmic.

wmic computersystem get manufacturer,model:

Manufacturer  Model
MSI           MS-7982

WSL support has been added.

Does wmic have an option to exclude Caption from the output?

Do know that wmic is just an inflexible legacy executable to interface with WMI from the ol' DOS shell.
You would typically query WMI/CIM from PowerShell, this also gives you the ability to easily drop the "Caption" header - for example like this:

# Probably most common:
(Get-CimInstance -ClassName CIM_OperatingSystem).Caption

# Faster
[System.Management.ManagementObjectSearcher]::new("SELECT Caption FROM Win32_OperatingSystem").Get().Caption

Also, with WSL2 there is no guarantee that the kernel has -Microsoft in its name as the user can use any linux kernel they want, so basing detection off of that is a little wonky. Even by default, my /proc/version on WSL2 Ubuntu 18.04 now reads:

Linux version 4.19.67-microsoft-standard (oe-user@oe-host) (gcc version 8.2.0 (GCC)) #1 SMP Sun Aug 18 13:37:54 UTC 2019

and uname -r :

4.19.67-microsoft-standard

The "microsoft" is lowercase now, so the current detection method does not work anymore already even with the (for now) default kernel.

I'm aware though Cygwin, MSYS and MINGW can access it through bash/`sh so we're limited to how it works in that sort of environment.

Does /proc/version always contain Microsoft?

[jantari]

I'm aware though Cygwin, MSYS and MINGW can access it through bash/sh so we're limited to how it works in that sort of environment.

You can call powershell.exe (or any other Windows executable) from WSL:

jantari@AMDESKTOP:~$ powershell.exe -Command "(Get-CimInstance -ClassName CIM_OperatingSystem).Caption"

that returns just Microsoft Windows 10 Pro in a single line, nothing more.

/proc/version will likely always contain [mM]icrosoft for the kernels Microsoft compiles and ships, but not for any kernel the user installs in WSL2.

I do see three promising environment variables in my WSL2 though:

$WSLENV (empty for me)
$WSL_DISTRO_NAME (contains 'Ubuntu-18.04' for me)
$WSL_INTEROP (contains '/run/WSL/8_interop' for me)

I'm not great at *nix-sh, but if there's an IFDEF-like statement that could work. $WSLENV is probably always declared, even if it's empty.

Fixed the WSL2 detection: 46b6802

Initial Windows support is done here: #22

Please test it out!

Suggestion: Running on Windows 11 WSL2 - make the text more generic - confusing when it shows "on Windows 10 [WSL2]" when I'm actually running Windows 11 - there is no difference to the detection code so just drop the 10?
