The course is an in-depth coverage on Linux system fundamentals (the essentials of Linux) as well as advanced administration including monitoring and troubleshooting. It starts with Linux environment and then jumps to Bash Shell scripting/programming which is essential for any serious Sysadmin.

Then it moves on to describe important concepts and aspects of Linux sub-systems like User/Group/Process Management, Automated Job Scheduling, Backup, Networking, package management, installation, event log files, monitoring and troubleshooting aspects which are necessary to perform regular day-to-day operations efficiently on a Linux System.
