Get gnu/linux hardware information

I just found this cool tool called dmidecode which “decodes your computer’s DMI (some say  SMBIOS) table contents in a human readble form” and basically spits out detailed information of your system hardware. For example to see what type of RAM memory you have on your motherboard just type as root

dmidecode –type=17.

Similarly if you want to check your processor’s details

dmidecode –type=4

The type parameter can be set to a specific number depending on the hardware you want to investigate. The full list of supported types is found in the dmidecode manual accessible through > man dmidecode. You can use the command without specifying a type in which case you’ll get a really long list of information.

UPDATE:

You can also get the similar information using keywords. For example

dmidecode –type=memory

is the same as using type=17.

The supported keywords are
bios
system
baseboard
chassis
processor
memory
cache
connector
slot
