LINUX Command Line Fundamentals
All are welcome to this course. Though this course is focused for new Linux users, there is content for the experienced Linux users as well. Learning the command line is challenging and takes a lot effort. It’s not that it’s so hard, but rather it’s so vast. Unlike many other computer skills, knowledge of the command line is long lasting. The skills learned today will still be useful ten years from now.
This course is created in a logical sequence each covering some aspect of the command line experience, which will help you understand how it works in real time and how it is setup from the Administration point of view and what are the channels in which the connection can help to communicate with the server, much like a tutor sitting next to you guiding you along.
Another goal is to acquaint you with the UNIX way of thinking, which is different from the Windows way of thinking. Along the way, we’ll go on a few side trips to help you understand why certain things work the way they do and how they got that way.
