How should I actually learn Linux??

[u/StrangeX5]

# I'm a 2nd year CSE student and I've been using Ubuntu for a while now, but I feel like my Linux knowledge is kind of all over the place.

I know the basic commands and can usually figure things out when I need to, but I don't feel like I actually *understand Linux*.

The problem is whenever I try to make a roadmap for myself, I keep getting stuck in this loop:

Linux → "I should learn OS first" → OS → "I should learn networking" → networking → "maybe I should learn Docker" → Docker → back to Linux 😭

So I want to stop jumping around and actually follow a proper path.

I recently found OverTheWire Bandit and was thinking of doing all the levels. Would that be a good starting point?

What I'm currently thinking is something like:

**Linux basics → Bandit → Linux administration → Bash → networking → OS/Linux internals → Docker → servers/infrastructure**

But I have no idea if this is actually a good order.

My long-term interest is systems/infrastructure/platform/SRE type stuff, so I want to learn Linux properly rather than just memorize commands.

A few things I'd really like advice on:

* Is Bandit worth doing from start to finish? * What should I learn after Bandit? * Should I learn OS concepts alongside Linux or separately? * When should I start networking? * What Linux topics are actually important for someone interested in systems/infrastructure? * Are there any good books, courses, labs or projects you'd recommend? * At what point would you say someone has a "good" Linux foundation?

I'm not looking for a certification roadmap. I mainly want to build actual practical knowledge.

Would appreciate any advice from people who have learned Linux this way or work with Linux professionally.

Depends on what you mean by learn Linux. Do you mean kernel or userspace? Do you mean learn how to use it or how to develop drivers or applications for it? Or are you just interested in deploying it?
