SYNOPSISacpihelp <option>... [<name-prefix>|<hex-value>]
DESCRIPTIONThis manual page briefly documents the acpihelp command. The option list is taken from the acpihelp interactive help.
acpihelp provides descriptive text for AML and ASL keywords, methods, and opcodes.
Much more detailed documentation may be found at http://www.acpica.org/documentation/.
If neither a <name-prefix> or a <hex-value> is provided, acpihelp will do the logical equivalent of a "display all."
A default search (that is, a search with no options) and a <name-prefix> can mean two different things: (1) if <name-prefix> does not start with an underscore, find ASL operator names, or (2) if <name-prefix> does start with an underscore, find ASL predefined method names.
