NAME

       acpihelp - ACPI help utility

SYNOPSIS

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

DESCRIPTION

       This  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.
