The Linux Institute is a free online resource for learning Linux. None of what we publish is gated. The newsletters are the easiest way to get new guides, AI tooling breakdowns, and security deep-dives as they land — and the easiest way to unsubscribe if they stop being useful.
We send four emails. None of them are mandatory. Subscribe to one or to all four — the sign-up pages each have a one-click unsubscribe at the bottom.
A daily Linux tip you can actually use. One command, one workflow, one gotcha. Skim it in the morning queue.
Mon–Fri · 07:00 SAST
Best for: anyone who wants the terminal to feel less mysterious within the next month.
The week's worth of new AI tooling on Linux, broken down by what actually shipped and what's just hype. Includes opencode, Ollama, llama.cpp, local-LLM workflows.
Mondays · 08:00 SAST
Best for: developers using AI on a Linux box and tired of vendor-flavored coverage.
What changed in open-source security this fortnight: advisories, CVE breakdowns, hardening techniques for Linux systems. Plain English, no FUD.
1st & 15th · 09:00 SAST
Best for: sysadmins, DevOps engineers, anyone responsible for a Linux fleet.
One long essay every Thursday. Original Linux stories, interviews with working engineers, the kind of writing that gets clipped, printed, and reread.
Thursdays · 18:00 SAST
Best for: people who want the human, opinionated side of the Linux world.
Sometimes the only way to know if you'll like a newsletter is to read one. Here is a complete Terminally Online edition, exactly as it lands in subscribers' inboxes.
A daily Linux tip you can actually use. Read time: about three minutes.
Welcome back. Today's tip concerns a moment most people hit within their first month on Linux: an editor that won't quit.
You have a file open in nano or vim. You type :q. Nothing happens. You type :q!. A E37: No write since last change message appears. You do not know what to do next.
Three keystrokes, in order. Type them one at a time and watch the bottom of the screen:
:q! # quit, throw away changes
:wq # write, then quit (capital ZZ works too)
:q # quit cleanly (no unsaved changes)Hold Ctrl and press X. Nano will ask if you want to save. Press Y for yes, N for no.
The editor is trying to be a good citizen. Unsaved changes in a long-running session often mean an in-progress commit, an interrupted edit, or both. Worth a moment of thought before discarding.
When you are stuck inside a tool you did not choose to be in:
Ctrl-C. Most tools interpret that as “give up and exit.”Ctrl-D. Same idea, different byte.That's it for today's tip. Reply to this email if you want a tip on a specific topic — one of terminals, files, network, processes, users, packages, systemd. Tomorrow: how to clean up old kernels without breaking the boot loader.

Recent editions across all four streams. Each one is also published on the site at /resources.
What fills your disk, what to delete first, and why du sees the world differently than df.
Mistral's new small model, two Ollama releases, and a quiet pivot from three vendors in the agent tooling space.
What the advisory actually says, who is affected, what to patch first, and a 10-line mitigation script.
A profile of the engineer who refused to migrate the South African power utility's mail stack and what happened next.
Subscribe to one or all four. We do not send anything you did not ask for. The unsubscribe link in every email is one click.
Newsletter editions publish on the site later. Subscribers see them land, often with a link to the long-form site version within a day.
Reply to any issue. Someone who has been running Linux for fifteen years reads every reply. We answer, or we point you to a working answer.
Yes. Everything on the site, and every issue of every newsletter, is free. No paywall, no premium tier, no sponsored content. We make no money from your inbox.
We send what we'd want to read ourselves. Terminally Online follows real questions from users. Deep Tabs follows actual changelogs and pushes. Security follows actual CVEs. The Read follows a story that deserves a slow read.
Yes. Each stream has its own signup. You can add or drop streams at any time without affecting the others.
Truth on Tech covers AI and security across the broader web. The Linux Institute is the Linux-specific companion: more how-to, more hands-on, narrower lens. Both are written by the same team.
Every email has an unsubscribe link at the bottom that works in one click. Or reply “unsubscribe” and a real person removes you.
No. We do not sell, share, or trade email addresses. Signup details live in our newsletter provider only.
Same email, four streams. We will send you a confirmation link, then nothing but the issues you signed up for. Unsubscribe any of the four individually.
Free · No paywall · One-click unsubscribe in every email · We never share your address.
