Original Question:

So I have a used MacBook Pro running Big Sur and have acquired and assembled all I need for my first build (better late than never?).

I am now attempting to create my USB installer and am getting a Command Not Found message from Terminal.
sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume

Is it possible my used laptop doesn't have the commands required?
