intro - introduction to administration and privileged commands
Section 8 of the manual describes commands which either can be or are used only
by the superuser, like system-administration commands, daemons, and
hardware-related commands.
As with the commands described in Section 1, the commands described in this
section terminate with an exit status that indicates whether the command
succeeded or failed. See
intro(1) for more information.
