Yep

Closest comparison I can give of it is… It’s like clicking “Yes” when the User Account Control (UAC) popup appears on Windows when you’re installing stuff. That’s you, as an admin, confirming you want to perform whatever action is being performed.

sudo ... is perform an action/command as an admin.

As for the mods. A lot of the time it’s a matter of taking the files you downloaded, and dropping them in the game directory (or a directory within the game directory).

Once you do it manually once, you’ll see it’s pretty straight forward and you don’t really need the mod managers.
