A

dmidecode

program segítségével számítógépünk hardvereiről kaphatunk igen részletes információt. Lehetőségünk van egy adott típusú hardver adatainak lekérdezésére, ha pl. csak a processzorról kell adat:

[]$ dmidecode --type processor
 # dmidecode 2.10
 SMBIOS 2.3 present.
 
 Handle 0x0400, DMI type 4, 32 bytes
