Professionals holding the CompTIA Linux+ credential can explain fundamental management of Linux systems from the command line, demonstrate knowledge of user administration, understand file permissions, software configurations, and management of Linux-based clients, server systems and security.

Because of the growing popularity of enterprise-ready platforms such as Linux, both employers and professionals realize the importance of skill validation. The industry recognizes that a CompTIA Linux+ certification is a good indicator of foundational proficiency in everyday management of Linux-based clients and basic management of server systems.
