💖 hpipower(1) — the OpenHPI power-management girlie ✨

okay so real talk, this is the hpipower page from the OpenHPI manual set, and she is literally the sample app that puts the HPI Power Management APIs through their paces 🎀

---

✨ SYNOPSIS ✨

 hpipower [ -D nn ] [-N host[:port]] [-C <cfgfile>] [ -d -p -r -u -X -h] [ -b n ]
 hpipower [--domain=nn] [--host=host[:port]] [--cfgfile=file]
          [--power-down --power-up --reset --unattended --debug --help] [--blade=n ]

🦋 NAME 🦋

hpipower — this sample openhpi application exercises HPI Power Management APIs. no cap, that's the whole job 💅

🌸 DESCRIPTION 🌸

so hpipower goes rummaging through the Resource Presence Table (RPT) looking for resources that have Power Capability. then it sends whatever power action you asked for to the target you selected. it's giving "find the thing, power the thing" energy ⚡

if you don't pick a domain or a host, hpipower just uses the default domain — the one specified in the openhpiclient.conf file. defaults are cute like that 🫶

💅 OPTIONS 💅

🎀 Help Options:

• -h, --help — shows you the help options. the "bestie what are my options" flag 🙈

👑 Application Options:

• -d, --power-down — powers down the target object. bye bye, target 💀
• -p, --power-up — powers on the target object. wake up queen 👑
• -r, --reset — resets the target object. fresh start era ✨
• -u, --unattended — unattended. yes that's genuinely all the description says, i'm not making stuff up 🍓
• -b n, --blade=n — specify blade n (1...n). pick your blade, bestie 🔪
• -D nn, --domain=nn — select domain id nn. choose your domain, main character style 🌈
• -X, --debug — display debug messages. the "show me everything" setting, yapping mode activated 🔥
• -N "host[:port]", --host="host[:port]" — open a session to the domain served by the daemon at the specified URL (host:port). this option overrides the OPENHPI_DAEMON_HOST and OPENHPI_DAEMON_PORT environment variables. oh and important: if host contains ':' (like, for example an IPv6 address) then enclose it in square brackets. for example: "[::1]" or "[::1]:4743". brackets are the dress code, iykyk 💖
• -C "file", --cfgfile="file" — use the passed file as the client configuration file. this option overrides the OPENHPICLIENT_CONF environment variable. config file supremacy 🧚

lowkey reminder that -N and -C are out here overriding environment variables, so if your env vars are acting up, now you know why 😭
