# groups <username>

To delete a member from the wheel group:

1.Edit the file /etc/group.

2.Remove the username from the line with wheel::XX:<user1>,<user2>,<user3>.

Sudo command

Using the sudo (superuser do) command, a user can execute a command using the privileges of another user (often root), as specified in the /etc/sudoers file. The user is authenticated using his own password, not the root password. The /etc/sudoers file logs all commands and arguments.

Syntax:

sudo <command>

Configuring sudo

A system administrator configures the /etc/sudoers file to give groups or users access to some or all commands not authorized with their normal account. An administrator should log into the console server as a root user and edit the /etc/sudoers file by using the /usr/sbin/visudo command to configure sudo.

The sudoers file is composed of aliases and user specifications. When multiple entries match for a user, they are applied in order. Where there are conflicting values, the last match is used.

Since the sudoers file is parsed in a single pass, order is important. You should structure sudoers so that the Host_Alias, User_Alias, and Cmnd_Alias specifications come first, followed by any Default_Entry lines, and finally the Runas_Alias and user specifications.

An example of an /etc/sudoers file:

#User alias specification

User_Alias FULLTIMERS = millert, mikef, dowdy

User_Alias PARTTIMERS = bostley, jwfox, crawl

#Cmnd alias specification Cmnd_Alias KILL = /bin/kill Cmnd_Alias SHUTDOWN = /sbin/shutdown Cmnd_Alias REBOOT = /sbin/reboot Cmnd_Alias SU = /bin su

FULLTIMERS ALL = KILL, SHUTDOWN, REBOOT, SU

PARTTIMERS ALL = SHUTDOWN, REBOOT
