Recommendation _ Plan

 

What I recommend (realistic plan)

Since you’re serious, here’s how to use this week:

Day-wise breakdown

Day 1

Filesystem + commands + navigation
👉 create/delete/copy/move 100 times

Day 2

Permissions + users + ownership
👉 intentionally break permissions and fix

Day 3

Processes + monitoring + kill
👉 create CPU hog → debug

Day 4

Services + logs + systemctl
👉 install nginx → break → fix

Day 5

Disk + memory + packages
👉 fill disk → clean → expand

Day 6

Networking full day
👉 ping/dig/curl/ssh/ports

Day 7

ONLY troubleshooting labs (all 40)
👉 simulate real issues

No theory. Only terminal.

🔥 My honest advice (very important)

If you want real confidence, do this:

Setup:

Install:

  • Ubuntu VM or EC2

Then daily:

Break something intentionally
Fix it
Repeat

Examples:

  • stop nginx

  • delete config

  • change permission wrong

  • block port

  • kill DNS

  • fill disk

This teaches 10x faster than notes.

Final answer for you

Since you’re from CSE background and clearly disciplined:

👉 Yes, this is enough for Week 1 foundation mastery
👉 Not “expert”, but “job-ready”

And for DevOps/SRE → that’s EXACTLY what you need.
