✨ ON_AC_POWER(1) — on_ac_power 🔌 ✨

💖 NAME

on_ac_power - test whether computer is running on AC power

🎀 SYNOPSIS

on_ac_power

🦋 DESCRIPTION

okay so on_ac_power is literally the vibe check for your power supply 🔋✨ It checks whether the system is running on abundant power (like AC mains, a USB charger, etc.) instead of battery power. no cap, it's giving plugged-in energy 🔌💅

🌸 OPTIONS

None. 🙈 it really doesn't need any, it's already iconic as-is 👑

🧚 EXIT STATUS

• 0 (true) — System is on mains power ⚡ plugged in and thriving 💖
• 1 (false) — System is not on mains power 🔋 running on battery, bestie
• 255 (false) — Power status could not be determined 💀 the system just shrugged

💜 CAVEATS

⚠️ okay listen bestie, most desktops and servers have no power sensors, so they return 255 "unknown" 😭 for most purposes you'd want to treat this answer as implying mains power 🔌 — just note that 255 evaluates as false for the shell, so don't let that trip you up 🙈

ngl this one's lowkey important: the program currently provides only information known to the kernel 🧠 it doesn't (yet?) query userspace daemons such as nut which may provide further information 🌈
