ACPIHELP(1)

🎀 acpihelp ✨ ACPI help utility 🦋

🌸 NAME

okay so acpihelp is the ACPI help utility 💖 — the one-stop shop for ACPI vibes 🔥

🧚 SYNOPSIS

acpihelp <option>...  [<name-prefix>|<hex-value>]

💅 DESCRIPTION

bestie, this manual page quickly documents the acpihelp command 🫶 and the option list is pulled straight from the acpihelp interactive help, so you're getting the real deal 💜

acpihelp gives you descriptive text for AML and ASL keywords, methods, and opcodes. literally everything you need to know, no cap ✨

if you want the full deep-dive, the super detailed stuff lives at http://www.acpica.org/documentation/ 🌈

if you don't give it a <name-prefix> or a <hex-value>, it just does the logical equivalent of a "display all." iconic behavior 👑

now the default search (that's a search with no options) and a <name-prefix> can mean two totally different things 😭:

• if <name-prefix> does not start with an underscore, it finds ASL operator names 🔥
• if <name-prefix> does start with an underscore, it finds ASL predefined method names 🦋

the vibe check: the underscore changes everything, so don't forget it 💀
