Can you explain how the sudo command works in Linux?

The sudo command in Linux allows you to execute commands as another user, most often as the superuser (root), without needing to log in as that user.

How it works:

• When a user enters a command with sudo, the system checks the configuration file /etc/sudoers to determine if this user is permitted to execute commands with elevated privileges.
• If allowed, sudo runs the command with the privileges of the specified user (by default root).
• To confirm, it may prompt for the current user's password.

This allows for safe execution of administrative tasks without giving permanent root access, and it logs actions performed with elevated privileges.

Example:

sudo apt update

This will update the package list with administrator rights.
