partition.
Formats a partition for DOS.
Applies a DOS volume label.
Creates a DOS directory.

System Control
These commands provide system-wide information and control. Normal
users can run many commands to obtain system information; however, commands
that actively change the configuration of the system need to run while
you are logged in as root — or have utilized the su command to become the
superuser temporarily.
Administration
Some administration commands (shown in Table A-10) don’t fall neatly into a
category.
Table A-10
Command
passwd
su
Purpose
Administration Commands
Changes a particular user’s password. Any user can run this
command to change their own password. Only root can use
it to change someone else’s.
Switches to another user account without logging out of this
one. The best way to use this command is su - so your
filesystem path and other information are loaded.
