Rerun the last command as `sudo` (`sudo !!`)

[TheBrenny]

Description of the new feature / enhancement

Consider adding a new command to the sudo syntax (sudo !!) to allow it to rerun the previous command in an elevated session.

Scenario when this would be used?

As a sysadmin, I often find myself hopping between shells and always forget which commands need an elevated prompt and which don't. My immediate action is to just run the command normally, and when that fails because I'm not elevated, I use sudo !! to try again.

Press ⬆, Home, and then type "sudo ". Same amount of keystrokes.

The simplest workaround is to define a sudo function in your $PROFILE, like the one I use myself:

function sudo {
	begin {
		function convertToBase64EncodedString([string]$cmdLine) {
			[Convert]::ToBase64String([System.Text.Encoding]::Unicode.GetBytes($cmdLine))
		}
	}
	end {
		switch ($args[0]) {
			$null {
				sudo.exe pwsh -nol
				break
			}
			'!!' {
				$encoded = convertToBase64EncodedString "$(Get-History -c 1)"
				sudo.exe pwsh -e $encoded
				break
			}
			{ $_ -is [scriptblock] } {
				$encoded = convertToBase64EncodedString $_
				sudo.exe pwsh -e $encoded
				break
			}
			{ Get-Command $_ -Type Application -ErrorAction Ignore } {
				# pass as-is for native command
				sudo.exe $args
				break
			}
			{ Get-Command $_ -Type Cmdlet, ExternalScript, Alias -ErrorAction Ignore } {
				$encoded = convertToBase64EncodedString "$args"
				sudo.exe pwsh -e $encoded
				break
			}
			default {
				throw "Cannot find '$_'"
			}
		}
	}
}

This looks like a duplicate of #6.

I guess I gotta get better at using GitHub search.
