PROMPT_HOSTNAME(1)

🦋 PROMPT_HOSTNAME(1) 🦋

okay so this is a page from the fish-shell manual, and it's literally the shortest little glow-up you've ever seen. bestie, it's so chill.

✨ NAME ✨

prompt_hostname — prints the hostname, shortened, for use in the prompt 💅

---

🌸 SYNOPSIS 🌸

prompt_hostname

that's it. that's the whole synopsis. she's low maintenance, she's iconic, she ate and left no crumbs 🎀

---

💖 DESCRIPTION 💖

okay so prompt_hostname prints a shortened version of the current hostname, specifically for use in the prompt. and by "shortened" we mean it prints just the first component of the hostname — like, everything up to the first dot, and nothing after it. periodt. 🫶

so if your machine is being all extra with a big long name, this bad boy gives you the main-character part only.

---

🌈 EXAMPLES 🌈

here's the vibe in action — dropping it into a fish_prompt function like the queen she is 👑

function fish_prompt
    echo -n (whoami)@(prompt_hostname) (prompt_pwd) '$ '
end

# The machine's full hostname is foo.bar.com
>_ prompt_hostname
foo

see how the machine's full hostname is foo.bar.com but prompt_hostname was like "no bestie, we're giving foo" 😭 so clean, so demure.
