By default, a Linux user will log in as a default user with limited rights. For example, on the Raspberry Pi Operating System, there is a single default user, initially called "Pi", with their home folder that can be referenced as "~".
In the '''apt''' context here, '''sudo''' is needed for any action involving writing (such as '''install''', ''full-upgrade'', '''update''', ''autoremove''), but not for actions that just read (such as '''search''', ''show'').
: Elsewhere on this page you might notice [[#Running any MX executable with a terminal session left open|'''cd''']] can move round the file structure (without a "sudo"), but "sudo" is used with [[# Installing/Configuring the MX service and the -service parameter|'''cp''']] as that writes a file.
: Novice readers should exercise caution, because changing ownership, adding write rights, using "sudo", and even using "-R" or "-y" flags, can all make it very easy to inadvertently do the wrong action, even perhaps delete vital folders/files.
: '''For technical readers only''', "sudo" is further explained later [[#su_and_sudo]]) as giving super-user (root) rights when executing the instruction that follows for actions on files that are not in the current user's ownership or for which we don't have the necessary (read, write, execute) permissions.
