If you are new to Linux and need an introduction to the command-line there are several things to consider.
1. Get a Comprehensive Outline
It is easy to spend time learning those topics of interest and end up lacking the whole picture. If you are looking for resources to learn Linux at the command-line then look for a source that systematically provides learning on a wide scope so you understand the Bash shell, how commands work, the basics of shell scripting, etc. Spend the time and energy to learn those things you normally neglect.
2. Start at a Level You Can Understand
There is a lot of material available on the Internet that can easily be over your head. You have to start from the ground and work you way up. You cannot start at the half-way point as you will quickly get lost. Review the material to see if you can understand the opening chapters and if the content builds upon basics so you can gradually build your understanding.
3. Dedicate Keyboard Time
If you think there are shortcuts to the command-line, think again. Nobody can learn this stuff without “hands on”. If you find material that says it provides a shortcut, stay away as it will not work. Dedicate 50% of the time you want to learn to actual time on the keyboard. Read and try it out, that is the only way to learn.
4. Look for Material with Exercises
Having a step-by-step process to work through when learning a new topic can help you dramatically. It is easy to make mistakes when you are just starting out. Those mistakes can be very simple mistakes that lead to long hours of troubleshooting. So exercises will help eliminate much of that frustration as you start.
Recently, I did a review for a book that provides some of the above features. If you are looking for an introduction to the Linux command line you might take the time to check out this book as it seems to do a good job at getting people started.
