$ cat /proc/cpuinfo

Memory :

$ free
$ cat /proc/meminfo


$ df -h
$ sudo fdisk -l
$ hdparm -i /dev/device (for example sda1, hda3...)

  • cat /proc/cpuinfo is brilliant, never knew about this. Thanks – Zubair Feb 14 '10 at 9:24

lshw command is also really useful to get a lot of information about all the hardware !

hwinfo would be one way to do it.


sudo dmidecode command will also give you more hardware info than you ever wanted.
