I have worked with DOS and windows for twenty five years now. My only nix experience was with phone systems and hotel systems with which I administered through step by step procedures. I am now starting to learn a bit more command line Linux as I have started playing with raspberry pi computers and switched a couple of laptops to Xubuntu and Mint XFCE. 
As you probably guessed, a lot of the show went over my head, but it is fascinating to hear the possibilities for automation that are available if I could learn more of Bash commands. This series has been very helpful to me in developing a desire to learn more and find things that I could try to automate.  
Thank you very much for your hard work.
