Shell Script to List ACPI tables

ACPI (Advanced Configuration and Power Interface) defines platform-independent interfaces for hardware discovery, configuration, power management and monitoring, and these tables contain lots of useful information for low-level programmers such as myself. Here is a short shell script which I clobbered together a few days ago to list out the ACPI tables on a system together with a short description of each table where possible. #!/bin/bash # # Author: Finnbarr P. Murphy # Date: January 2015 # Purpose: List ACPI tables # License: BSD # TMP1=$(mktemp -u -p /var/tmp/ acpiXXXXXX) TMP2=$(mktemp -u -p /var/tmp/ acpiXXXXXX) TMP3=$(mktemp -u -p /var/tmp/ acpiXXXXXX) cat
