✨ S6-GETSERVBYNAME(8) ✨

okay so bestie, welcome to s6-getservbyname — it's a little command-line bestie for the getservbyname(3) function, and honestly? it's giving service name + protocol → port number conversion and it does it flawlessly. this lives in the System Manager's Manual, section 8, iykyk 💅

💖 NAME 💖

s6-getservbyname — a simple command-line interface to the getservbyname(3) function, converting a service name and protocol into a port number. that's it, that's the whole vibe 🎀

🌸 SYNOPSIS 🌸

s6-getservbyname name proto

like. two args. that's the whole thing. iconic behavior honestly ✨

🦋 DESCRIPTION 🦋

so what it does is: s6-getservbyname looks up the network services database for an entry containing name name and protocol proto. lowkey search-and-rescue but for services 🔍

once it finds it, it prints the corresponding port number to stdout, then exits 0. slay. perfect. no notes 🫶

and if it cannot find a related entry? it exits 1. that's the whole failure mode, bestie — no drama, no crash, just a very dignified 1 😭

🧚 EXAMPLES 🧚

on a standard machine with a correct /etc/services file and a non-garbled NSS configuration (fr fr, those matter):

s6-getservbyname smtp tcp

prints 25.

that's it. that's the example. she ate and left no crumbs 👑
