A few months ago I wrote out some recommendations around the same theme here. Extracts:

A good start is to install tldr. You use it like man, but it gives you shorter explanations – or rather, a short list of illustrative examples.

Going further, check out Fish instead of Bash. I haven’t use Fish yet, but it’s said to be much better for learning Linux commands as a beginner. Later on, you may switch to Zsh. In any case, hitting Tab once or twice will often give you a list of possible completions to the command you are typing.

Also, I hugely recommend reading at least one book about Linux. I'm now almost through with the O’Reilly book “Classic Shell Scripting” by Robbins and Beebe (ISBN 9780596005955). Despite the fact that it's 20 years old, it helped me hugely – primarily with the shell and its commands, but also with understanding things like file structure.

It presupposes some familiarity with Unix-like systems and with the shell, so if one’s just starting out, the book “Learning the Unix Operating System” may be better.
