Day 2 — Beginning My 40 Days AWS DevOps Journey

Today was Day 2 of my 40-day AWS + DevOps challenge.
I focused on strengthening Linux fundamentals because every DevOps job requires fast command-line skills — especially on EC2.

Here’s what I practiced today:

** File & Permissions **

chmod – make scripts executable
chown – fix file ownership
df -h – check disk space
du -sh – check folder size

** Processes & Services **

ps aux – list running processes
top – live CPU/RAM
systemctl status/start/restart – manage services (nginx, docker)

** Networking **

curl – check if a service/website is responding
ss -tulnp – check open ports

** Logs **

/var/log/ – main log directory
tail -f – watch logs in real time
journalctl -u – check service logs {This is for aws linux 2023}

** Pipes **
ps aux | grep nginx
tail -f messages | grep error
