Synopsis
sudo [options
]command
Executes a command as the superuser or as another user on the system.
Before sudo
executes command,
it will prompt for the current account password
(not root’s).
sudo
determines who is an authorized user by
consulting the file /etc/sudoers. If the current
user account is listed in /etc/sudoers and is
authorized there to run command, that user can
then run subsequent sudo
commands without being
prompted for a password. However, if five minutes (the default value)
passes between sudo
commands, the user will be
prompted again for a password at the next sudo
attempt, and given another five minute window.
By default, Mac OS X includes the admin group in
the sudoers
file and gives that group
authorization to run any command with sudo
. Mac OS
X accounts given administrator privileges become members of the
admin group, and thereby receive complete
sudo
privileges.
All attempts to use the sudo
command are logged to
the system log.
