WWCTL(1)

📦 version 4.7.1, in opensuse-leap 16.0

💅 wwctl-power-off 💅

ok so bestie, welcome to the wwctl-power-off page — it's the wwctl subcommand that handles the whole "cut the power" situation, and it lives in section 1 of the manual (that's the (1) at the top, iykyk). pull up a chair, we're getting into it. 🎀

✨ NAME ✨

wwctl-power-off — power off the given node(s). literally that's it, that's the whole job. 🔌

🌸 SYNOPSIS 🌸

wwctl power off [OPTIONS] [PATTERN ...]

🦋 DESCRIPTION 🦋

okay so this command will shutdown power to a set of nodes that you specify with PATTERN. it's giving "lights out, everyone" energy. 💀

now, these node patterns? a comma-separated list of individual patterns. and each pattern can be either of these two iconic things:

  • a full node name, or
  • a node range like node[01-03,05] — yes, with the brackets and the commas, she's fancy. 🌈
💖 pro tip from your girl: read the pattern carefully before you hit enter, because this is a power off command and there's no take-backsies built in. not me being dramatic, just being honest. 🫶

✨ OPTIONS ✨

  • --fanout=50 — how many commands should be executed in parallel. default is 50, so she's out here running fifty of them at once by default — main character energy fr fr. 🔥
  • -h, --help[=false] — help for off. the classic "what does this even do" button. 💅
  • -s, --show[=false] — only show the command which will be executed. perfect for a little vibe check before you commit — she'll tell you what she would do, without actually doing it. 🙈

🌸 OPTIONS INHERITED FROM PARENT COMMANDS 🌸

these bad boys come down from the parent command, so they're not unique to off, but they're still here and still slaying:

  • -d, --debug[=false] — run with debugging messages enabled. when you need the tea, she gives you the tea. 🍓
  • -v, --verbose[=false] — run with increased verbosity. not just the tea, the whole tea ceremony. ✨
  • --warewulfconf="" — set the warewulf configuration file. default is empty (""), so she'll do her usual thing unless you point her somewhere specific. 🎀

  • wwctl-power(1) — go read that one next, bestie, she's the parent of this whole situation. 🫶
