Challenges in Linux Administration?

[shivajikobardan]

TL;DR

learning linux to next level.

As you all know I got a job as a Linux Administrator Intern few months ago. I've finished Imran Afzal's course on udemy a month ago, which was 35.5 hrs long. I'm comfortable with Linux by now. But I feel I could do better. That's why I picked up a RHCSA course that I got for 15$ from reputed online site. Now, I want challenging problems of Linux like in programming there is leetcode, hackerrank etc. No, I don't need bash shell scripting for the job. I just need to perform basic activities.

I'm also thinking of purchasing RHCSA question bank from Ghada Atef on udemy after I finish this RHCSA course. What other activities could I do to improve my Linux skill.

I'm obviously using Linux in a vmware workstation pro and doing along with the course on laptop.

The most coomon tasks in Linux admin:
- maintaining the network connections
- maintaining and backing the filesystems
- workload leveling machines
- monitoring for vulnerabilities or odd workloads or odd sign-ons for users...
- maintaining the proper level of software updates
- identifying files based on some criteria to clean up some issue
- using the proc directory to learn things about the machine

I would start with scripts that can walk the filesystems looking for duplicates by name, by size, by date, by CRC check...

The trouble is the tasks in Linux Admin are so varied that your best bet is to know how to craft scripts to get the job done.

Look for linux cookbooks that will give you the pieces of script/commands needed to get something. Here's one I found on Amazon:

workload leveling machines

With a good 19" rack, they seem pretty level to me.

The thing is that I don't need scripts so why learn it now? I do plan to learn scripting in the future, but atm I'd rather work on solidifying my programming concepts using c++ and javascript.
