What does 'sudo' do?

sudo stands for "superuser do." It is a command used in Unix-like operating systems to allow a permitted user to execute a command as the superuser (root) or another user, as specified by the security policy.

Key Points:

• Privilege Escalation: It grants temporary elevated privileges to perform administrative tasks.
• Security: It helps prevent unauthorized access by requiring users to have permission to run specific commands.
• Logging: Commands executed with sudo are typically logged for auditing purposes.

Example:

To install a package, you might use:

sudo apt install package-name

This command runs the installation with superuser privileges, allowing it to modify system files.
