sudo is a utility that allows users to execute commands with the privileges of another user, typically the root user. On a Linux system, the sudo configuration is stored in the /etc/sudoers file, which specifies which users are allowed to use sudo and which commands they are allowed to run.
Here are a few examples of how you can configure sudo on a Linux system:
Allow a specific user to run all commands using sudo:
To allow a specific user, such as john, to run all commands using sudo, you can add the following line to the sudoers file:
john ALL=(ALL) ALL
This will allow the user john to run any command using sudo.
Allow members of a specific group to run all commands using sudo:
To allow members of a specific group, such as admin, to run all commands using sudo, you can add the following line to the sudoers file:
%admin ALL=(ALL) ALL
This will allow all members of the admin group to run any command using sudo.
Allow a specific user to run only a specific command using sudo:
cent ALL=(ALL) ALL
