Now, if you want something a bit more polished, there’s lsb_release -a. The “lsb” stands for Linux Standard Base—fancy, right? Run that, and it spills out the distributor ID, release number, and even a codename. You might see something like “Ubuntu 22.04 LTS (Jammy Jellyfish).” Yes, that’s a real codename. Linux developers have a sense of humor.
Watch out, though: not all distros have this installed by default. If you get a “command not found” error, just laugh it off and fall back to cat /etc/os-release. It’s your trusty backup plan, like a spare tire for your digital car.
And honestly? I use this one the most when I’m showing off. It just looks professional. “Oh, you want to know the OS version? Let me just lsb_release -a real quick…” Cue impressed silence.

hostnamectl for the Overachievers
Are you running a system with systemd? (Spoiler: almost everyone is these days.) Then you’ve got a secret weapon: hostnamectl. Type that alone, and it gives you the OS version, kernel version, architecture, and even your static hostname. It’s like the Swiss Army knife of system info.
I love this one because it’s a single word to remember. No flags, no special syntax. Just hostnamectl, and the information parade starts marching across your screen. Boom—mic drop.
But here’s the ironic part: it’s technically not just for your OS version. It also tells you things like your “Chassis” type (desktop, laptop, server). I once saw “Chassis: vm” and thought, “Well, that explains why I feel so trapped.” See? Even the terminal gets meta.
