Rex::G...::File(3pm)

💖 Rex::Group::Lookup::File — the Perl man page, but make it bestie-coded 💖

okay so this is Rex::Group::Lookup::File, from the User Contributed Perl Documentation collection, section 3pm. It's a Perl module. It's cute. It reads hostnames out of a file. That's the whole assignment and she ate. 🎀

✨ NAME ✨

Rex::Group::Lookup::File — literally just read hostnames from a file. that's it. that's the job. no cap. 🦋

---

🌸 DESCRIPTION 🌸

Bestie. Listen. With this module you can define hostgroups out of a file. Like, you got a file with hostnames in it? boom, that's a hostgroup now. iconic behaviour honestly. 👑

---

🫶 SYNOPSIS 🫶

the vibe check, in code form:

use Rex::Group::Lookup::File;
group "webserver" => lookup_file("./hosts.lst");

that's the whole thing. she's simple, she's elegant, she's main character energy. ✨

🌈 EXPORTED FUNCTIONS 🌈

💅 lookup_file($file) 💅

ok so with this function you can read hostnames from a file. and here's the part where i need you to lock in: every hostname goes on one line. one host, one line. that's the format. don't be weird about it. 🍓

like so:

group "webserver"  => lookup_file("./webserver.lst");
group "mailserver" => lookup_file("./mailserver.lst");

look at that alignment. the spacing. the symmetry. not me being obsessed with two lines of Perl 😭✨

so yeah, that's the whole man page bestie. go forth and group your hosts. slay. 💜

okay bye, this was documented as part of Perl v5.40.1, dated 2025-10-03, and yes she's still serving after all this time. periodt. 💖
