Сбор информации о железе в Linux

Собрать информацию о железе в Linux можно командой dmidecode.

# установка на CentOS
yum install dmidecode

# установка на Debian
apt-get install dmidecode

# Запрос списка групп, по которым есть информация
dmidecode -t

> Valid type keywords are:
>   bios
>   system
>   baseboard
>   chassis
>   processor
>   memory
>   cache
>   connector
>   slot
