How To Add, Delete, and Grant Sudo Privileges to Users on a FreeBSD Server

To add, delete, and grant sudo privileges to users on a FreeBSD server, you can use the adduser, pw, and visudo commands.

Here are the steps to follow to add, delete, and grant sudo privileges to users on a FreeBSD server:

1. To add a new user to the server, use the adduser command. For example, to add a user named "john" with a home directory at /home/john, you can use the following command:

adduser

Follow the prompts to set the user's password and other details.

2. To delete a user from the server, use the pw command with the userdel option. For example, to delete the user "john", you can use the following command:

pw userdel john

3. To grant sudo privileges to a user, edit the /usr/local/etc/sudoers file using the visudo command. For example, to grant sudo privileges to the user "john", you can add the following line to the sudoers file:

john ALL=(ALL) ALL

This will allow the user "john" to run any command with sudo privileges.

Note: The adduser, pw, and visudo commands have many options and features available for managing users and sudo privileges on a FreeBSD server. Consult the documentation and online resources for more information on the various options and features available with these commands. It is recommended to use these commands with caution, as improper use can cause security issues or disrupt the operation of the server.
