[b]Description[/b]

Every journey begins with the first step. Take those steps towards a career as a GNU/Linux System Administrator with this courseThis class is for the individual who wants a strong understanding of the GNU/Linux operating system and to potentially prepare for the RHCSA, RHCE, LFCS, CLNP certifications. This course was designed to teach someone with little to no experience with the Linux operating system. It is meant to cover the necessary skills required for an entry level Systems Administrator to successfully manage a Linux system. This is a comprehensive course that will cover many of the topics an entry level Linux Systems Administrator would deal with while performing their day-to-day functions. Once a student has completed this course, they should have the skills required to successfully fulfill the roles and responsibilities of an entry level GNU/Linux Systems Administrator. Students will learn about the history of GNU/Linux, the components that makeup GNU/Linux, the basics of the GNU/Linux command structure, how to get help with GNU/Linux, an introduction to the GNU/Linux environment, how to work with text data, the components of user and group accounts and how to manage them, the GNU/Linux directory structure and how to navigate it, the fundamentals of file and directory management, how to identify and manage GNU/Linux processes, and an introduction to TCP/IP management. After completing this course, a student should be prepared to expand on their knowledge to become an advanced level GNU/Linux Systems Administrator.
