Hey thanks for this, nushell looks really interesting! I really like the idea of an objective shell but don't like the verbosity of PowerShell inputs. I think if you go through my post history I actually describe wanting something like Nushell, not knowing it existed!
Tbf most common PowerShell commands have short aliases for interactive use. I like that I can use the long forms in scripting and aliases on command line.
For example in my PS (unsure who created aliases because I think some aren't default) I have both "ls" and "dir" for "Get-Childitem", "wget" for "Invoke-Webrequest" and so on.
