Query System Specs in Linux
Here are some ways to find the specs for your system via the Linux terminal.
Motherboard
You might want to know what your motherboard manufacturer and model are. Run:
sudo dmidecode -t 2
And get:
# dmidecode 3.3
Getting SMBIOS data from sysfs.
SMBIOS 3.0 present.
Handle 0x0002, DMI type 2, 15 bytes
