Enjoy this list of instructional videos I have found on YouTube. You may not expect YouTube to carry much content for serious Bash Shell programmers or students preparing for IT certification, but it is there - and available for no cost. You can be a beginner and develop your Bash Shell and computing workflow for free. You can be an intermediate or advanced Bash Shell script creator and catch lectures and tutorials from others who are among the best in the world.
Whether the topic is shell scripting, writing more efficient Bash code, learning to use tools like grep or awk, or interfacing with large software packages, you can usually find someone talking about it on YouTube. Now, forsake those petty political videos and never ending streams of social media clickbait. Brew a coffee and take an hour or two to understand brace expansion or making better loops. Spend a weekend learning how use grep, awk, or fzf. Watch and learn how Bash Shell programmers refine their workflow.
