nologin(5)

✨ nologin(5) ✨

okay bestie so this is a page from the File Formats Manual, and it's about a little file that goes hard 💅. it's giving tiny file, massive consequences. no cap.

---

🌸 NAME 🌸

nologin — the way to stop unprivileged users from logging into the system 🚫🫶

---

💖 DESCRIPTION 💖

okay so here's the tea. if the file /etc/nologin exists and is readable, then login(1) is gonna be like "nope, root only" — it will allow access only to root. everybody else? their logins get refused, periodt. 😭

and it's not even a silent rejection, which is honestly so considerate of it. other users get shown the contents of this file when they try to log in. so yes, /etc/nologin is literally a little note you leave for everyone. iconic behavior fr fr. 💌

the whole point? it's a simple way of temporarily disabling all unprivileged logins. like a "we're closed for a sec, don't @ me" sign but for your whole machine. very main character energy for a file that's usually empty. 💀

✨ reminder: it has to exist and be readable for any of this to kick in. no file, no vibe check.
