✨ ifmetric(8) ✨

okay bestie, welcome to the manual page for ifmetric — a System Manager's Manual moment, section 8, we're in the big leagues 💅

🌸 NAME 🌸

ifmetric — An IPv4 route metrics manipulation tool

🎀 SYNOPSIS 🎀

ifmetric INTERFACE [METRIC]

🦋 DESCRIPTION 🦋

so like, ifmetric is a Linux tool that sets the metrics of all IPv4 routes attached to a given network interface — all at once, in one go, no cap. 🫶

and why would you even want that? because it lets you change the priority of routing IPv4 traffic over that interface. and here's the key tea: lower metrics correlate with higher priorities ⭐ so small number = big main character energy.

ifmetric uses the Linux NETLINK interface to manipulate the routes. and because of that? it's compatible with routes created with the new iproute2 utility. slay. 🔥

💖 OPTIONS 💖

okay so the arguments are positional, not flags, keep up bestie:

  • INTERFACE — you should specify the interface name as the first parameter.
  • METRIC — the second parameter should be the new metric. if you omit it, the metric 0 (the highest priority one) is used. default queen behavior 👑

⭐ RETURN VALUES ⭐

  • 0 — Success ✨
  • 1 — Failure 😭
