So I desire to improve my knowledge About shell and the Command line interface. Know some commands and can quite navigate my way to an extent through the CLI.
But I still want to improve more by buying a course on shell from Udemy. Pls do anybody know any hack or the best way to buy (possibly download it into my PC) It's my first time trying to buy I'm not quite sure how it best works...any ideahow to best buy pls?

It's too cheap to buy to be thinking of a hack


U think God will give u job after u use phoney ways to gain your knowledge?

And I future you'll want to create your own course and sell

Have you read the book, "The Linux command line" by William Shots. And "Learn enough command line to be dangerous"? These books were an eye-opener for me, from basic shell navigation to I/O redirections, like grepping and using wild cards, file permissions, bash scripting, and lots more. I find those shell tutorial videos too repetitive and boring.
Also, the ALX SE course is another good avenue to practice what you have learned about the Unix command line.
