Could you recommend a source for learning how to use the command line? In the past I struggled with understanding the basic commands and the various flags. I've found it difficult to find good documentation, but I would like to learn
This is a fun game approach to learning some bash basics.
I highly recommend O'Reilly's Learning the Bash Shell in paperback form: https://www.oreilly.com/library/view/learning-the-bash/0596009658/.
The other responses you've received so far don't offer much insight into the historical background and underlying mechanics of the shell, which are crucial to understanding the "Why?"s of command-line quirkiness.
A 20 year old paperback book seems like a bad choice.
It's a 36 y/o language, mate. I still reference my copy all the time, and found it to be a great definitive resource when I was learning.
How many bash 4/5 features are you seriously using on a regular basis? What do you think is out-of-date?
Are you under the impression that that language hasn't changed?
Bash has had some nice minor features and syntax sugar added, but the fundamentals are entirely the same. All the examples in the book work just the same today as they did when it was written.
What was added in 4.X or 5.x that you can't live without? What do you think has changed that merits inclusion?
Thanks for your reply. I agree the 'why' is important, for me that usually makes things more intuitive
Find a problem or project that requires the terminal to solve it, follow the instructions laid out, and execute. Once you’ve done it, try tolook back at what you did and understand exactly what was going on under the hood. You can’t just “study terminal“ or something, the best way to learn is by doing. Just come up with simple things that need it. For instance, a Linux distribution that requires you to download a few drivers. That’s a really good building block right there. Gets you to understand how to navigate file paths on your computer from your terminal, how to know where to look for things and such
TBF ChatHPT is probably your best bet
It’s been a long time since I learned, so I don’t remember exactly what I used, but at a cursory glance, this one looks good:

Also, learning to read man pages will help a lot. Here’s an article on that:

I do remember using “terminal cheat sheets” like this:

Thanks for the very practical resources!
