GETNAMEINFO(1)

✨ GETNAMEINFO(1) ✨

okay so this is a page from the User Contributed Perl Documentation and it's literally called GETNAMEINFO(1), iykyk 💅

🌸 NAME 🌸

"getnameinfo" — a command-line tool that wraps the getnameinfo(3) resolver, and honestly? she's serving 🎀

🦋 SYNOPSIS 🦋

getnameinfo [options...] address port

💖 DESCRIPTION 💖

So basically this tool is a cute lil command-line wrapper around the getnameinfo(3) resolver function, no cap 🫶 It does one single reverse lookup — just one, babe — to turn an address and port number into its host and service names.

Where this really eats? Debugging names resolution problems 🔥 Because it lets you inspect the behaviour of getnameinfo(3) itself, outside of any real program that's trying to use it. Like, you get to see the function alone in the wild, being itself, with no other code involved 😭 iconic.

💅 OPTIONS 💅

• --address, -A ADDR — the numerical form of the address you wanna look up. If you don't supply it, the tool will just use the first positional argument instead ✨
• --port, -P PORT — the port number to look up. If you don't supply it, it grabs the second positional argument 🍓
• --dgram — sets the NI_DGRAM flag, so it looks up a SOCK_DGRAM (udp) port allocation instead of a SOCK_STREAM (tcp) one 👑 lowkey the most important flag here fr fr
• --help — displays a help summary and exits 🧚 super simple, we love her
