Resources to further learn Linux
What resources would you recommend to me for delving deeper into Linux operations while maintaining the fundamentals?
By that I mean I’ve been using Linux for a few years now - Ubuntu, Fedora, Ubuntu Server and recently playing with Omarchy. So I’m kind of comfortable with basic commands, navigating a file system, finding reading moving files etc. I’m not scared of a terminal 😀 but I find I still go to Google search or AI for more intermediate or advanced commands and I’d like to have a better wholistic understanding and how to administer linux system properly and troubleshoot better.
A focus of mine is network operations.
I saw the CompTia Linux+ but it seems to get some mixed reviews, is Linux System Administration Essentials (LFS207) worth the cost?
I bounce around between various YouTube videos but am chasing something more concise and structured
Any suggestions welcomed!
Cheers

You can google the title of each book plus PDF, should come up on the Internet Archive
Hungry Minds Linux+ Certification Bible
How Linux Works What Every Superuser Should Know
Sybex Linux Administrator Street Smarts, A Real World Guide to Linux Certification Skills
Apress Pro Bash Programming, Scripting the GNU-Linux Shell
OReilly LINUX System Administration
MCGraw-Hill Osborne Linux Administration, A Beginners Guide
MCGraw-Hill Osborne Linux, The Complete Reference
All my copies of these books are from the 2000s, there are probably more recent editions now. Will still teach you a lot.

gonna get some hate but honestly daily driving linux from scratch while in uni back in the day really helped me. especialy in the troubleshooting side of things. knowing how things work and talk help alot when figuring out which layer is broken or learning some kernel level calls on things help to understand alot of things.

The best way to learn is to build something that you will use.
Then break it.
Then fix it.
You could read 100 books and (for example) never learn the pain of a hidden space character in a .yaml file.

The UNIX and Linux System Administration Handbook, 5th edition
It's not for beginners. It's for those wants to go deeper and broader in a systematic way.

I suggest you try to do objective-based projects and "what happens if" scenarios.
For Linux troubleshooting you can try SadServers.com ;-)

Get your red hat certified system administrator cert, if you're going for a cert. There's free resources online you can find, Sander Van Vugt has great material for that exam, and video series on O'Reilly. If you're already savvy, you can complete the whole course in the 10 day free trial on O'Reilly.
RHCSA is a fully practical exam, no multiple choice or anything like that.

Try the Linux Upskill Challenge, a free, structured course where you set up a real server and work through daily sysadmin tasks, like SSH hardening, logs, cron, and networking basics. It’s concise, practical, and has a supportive community. Exactly the kind of structure YouTube lacks.
