ZSHUTDOWN_NOTIFY(8)

💖 zshutdown_notify — the zshutdown_notify(8) page, but make it cute 💖

okay bestie, this one lives in the System Manager's Manual section 8, so you know it's giving sysadmin main character energy 👑

✨ NAME ✨

zshutdown_notify — warn your users that the machine is about to go bye-bye, via Zephyr 🦋

---

🌸 SYNOPSIS 🌸

zshutdown_notify

that's it. no flags. no options. no drama. she simply is 💅

---

🎀 DESCRIPTION 🎀

okay so here's the tea, fr fr. zshutdown_notify reads standard input until it hits EOF, and then — then — she sends a Zephyr notice. 🕊️

And what's in that notice, you ask? Three things, no cap:

1. the official hostname,
2. the collected input (aka everything you just piped in),
3. and a warning message,

…all chillin' together as the message body of the notice. 📬

The notice gets sent to:

• class FILSRV
• instance <hostname>
• recipient "*"

where <hostname> is the official hostname of the sending host. (Not a nickname, not a vibe, the official one. ✨)

The whole point, the entire reason she exists: anybody using resources on the sending host is expected to subscribe to these messages, so that when a shutdown is impending they get warned. It's a courtesy heads-up. A little "hey girl, the lights are going out" 🫶

And lowkey the cutest detail — zshutdown_notify is usually invoked from inside /etc/shutdown. She doesn't just show up on her own, she gets called 😭 iconic.
