Sys::Hostname(3pm)

💖 NAME 💖

Sys::Hostname — ok so this module will try literally every conceivable way to get your hostname. every single one. it does not give up easily, and honestly? main character energy.

---

✨ SYNOPSIS ✨

use Sys::Hostname;
my $host = hostname;

that's it. that's the whole vibe. 🎀

---

🌸 DESCRIPTION 🌸

Bestie, here's the tea: Sys::Hostname attempts several methods of getting the system hostname, and then it caches the result — so it does all that detective work once and then chills. 🧚

It tries the first available of these, in this exact order:

1. the C library's gethostname()
2. $Config{aphostname}
3. uname(2)
4. syscall(SYS_gethostname)
5. hostname
6. uname -n
7. the file /com/host

Like, it is thorough thorough. it's giving backup plan to the backup plan to the backup plan. 💅

And if all of that fails? 😭 it croaks. no hostname, no peace. periodt.

One more thing you need to know, and this is lowkey important: all NULs, returns, and newlines are removed from the result. so what you get back is clean, no stray whitespace gremlins hiding in there. ✨
