Find Hardware Specs in Linux
It might be important, at some point, to know what your computer really is. The "lshw" tool tells you the truth about what do you have in hand. This tool also can be filtered by components such as memory, disk, graphic or network.
To get all specs for your computer simply type:
sudo lshw
Memory check
sudo lshw -C memory
To see the status of your memory, simply type:
cat /proc/meminfo
CPU check
sudo lshw -C cpu
or
cat /proc/cpuinfo
Disk check
sudo lshw -C disk
or
sudo hdparm -I /dev/sda
You might have to run: sudo fdisk -l to find out where your drive is.
Network check
sudo lshw -C network
or
lspci | egrep 'Ethernet|Network'
Graphic (GPU) check
sudo lshw -C display
or
lspci | egrep 'VGA|Display'
Is there any discrepancy between what the salesmen told you and the computer specs?
