> npm and gem behave like this

No, `npm` has a couple aliases like "i" for "install", but you can’t use "in", "ins", "insta", etc. It has "view" and "version" but "v" is an alias for "view".

`gem` does work like this (#TIL), although it has some hard-coded aliases: while its help page says "Commands may be abbreviated, so long as they are unambiguous", `gem i` works as `gem install` even if there’s a command "info". If you try `gem in`, it does complain that it’s ambiguous.
