= Using sudo to assign administrator privileges
Add users to the [directory]`/etc/sudoers` configuration file to allow them to use the [command]`sudo` command. For these users, the [command]`sudo` command is run in the user’s shell instead of in a root shell. As a result, the root shell can be disabled for increased security.
The administrator can also allow different users access to specific commands using the sudo configuration. Administrators must use the [command]`visudo` command to edit the [directory]`/etc/sudoers` configuration file.
To assign full administrative privileges to a user, type [command]`visudo` and add the following line to the user privilege section after replacing _USERNAME_ with the target user name:
----
USERNAME ALL=(ALL) ALL
----
This line allows the specified user to use [command]`sudo` from any host and execute any command.
To allow a user access to specific commands, use the following example after replacing USERS with a target system group:
----
%USERS localhost=/usr/sbin/shutdown -h now
----
This command allows all members of the _USERS_ system group to issue the [command]`/sbin/shutdown -h` as long as the command is issued from the console.
The man page for [command]`sudoers` has a detailed listing of options for this file.
