You have created a wonderful course on Linux Basics Course for absolute beginners like us and shell scripting module.
Is it possible for you to take this to next level and launch a complete course for Offcial RHCSAv8 certification course ? This is I believe most basic linux certification and skills badly needed due to wide deployment of Red Hat as OS in most of the enterprises.
This link provide all basic building blocks of RHCSA exam and from there onwards if you wish you can take this higher to RHCE etc.
with best regards
