Running WSL from Windows Powershell Terminal

I was told it was this easy...

wsl -e "simple_script.sh"

But that resulted in a whole heck of a lot of errors like this:

> wsl.exe -e "ls"
<3>WSL (9) ERROR: CreateProcessParseCommon:711: Failed to translate \\wsl.localhost\Ubuntu\home\nosferatu

Normally when I run wsl, I run it via a function of mine called bash -- and what it eventually does is call:

wsl.exe -d Ubuntu;

And I've just read that -- to set the default profile of Ubuntu you can do this:

wsl --setdefault Ubuntu

So I did that.

AND THEN THE ERROR WENT AWAY!

So -- this error:

<3>WSL (9) ERROR: CreateProcessParseCommon:711: Failed to translate \\wsl.localhost\Ubuntu\home\nosferatu

MEANS --

I don't know what profile to use by default when running WSL!

Go figure!

wsl.exe -e "ls" | % { wh "- $_  " -f red -n}

<3>WSL (9) ERROR: CreateProcessParseCommon:711: Failed to translate \\wsl.localhost\Ubuntu\home\nosferatu
