Linux is an operating system, like Windows or macOS. It’s what controls the hardware and lets you run programs.

Here’s the straight deal:

It’s free and open-source.

It’s fast, stable, and secure.

It runs most servers, supercomputers, and cloud systems.

Android is built on a Linux-based kernel.

Regular people use it for coding, servers, cybersecurity, and old PCs that need new life. Power users love it because you control everything.

Standard update (what you should run regularly)

sudo apt update
sudo apt full-upgrade
sudo apt autoremove

Reboot only if the kernel updated:

sudo reboot

One command, no prompts

sudo apt update &&sudo apt full-upgrade -y &&sudo apt autoremove -y

Snap packages (Ubuntu uses these)

sudo snap refresh

Check if a reboot is needed

reboot-required

(or just reboot if you don’t care)

Major version upgrade (example: 22.04 → 24.04)

Only do this when you actually want a new Ubuntu release:
