lynis:tldr:95279

This command consists of three parts:

1. sudo: It is a command in Linux systems that allows a user with proper permissions to execute a command as a superuser or root user. The "sudo" command ensures that the subsequent command is executed with administrative privileges.

2. lynis: It is a security auditing tool used to assess the security status of a system. Lynis performs system and software audits, checks for misconfigurations, identifies security vulnerabilities, and recommends improvements to enhance the system's security.

3. update info: These are parameters passed to the "lynis" command. In this case, "update" is a parameter that instructs the lynis tool to update its security database, which contains information about vulnerabilities and configuration checks. By updating this database, the tool ensures that it has the latest information to perform accurate security assessments.

Therefore, the command "sudo lynis update info" will execute the "lynis" tool with administrative privileges, updating its security database with the latest information.
