Linux is an enthusiast's delight. However, getting detailed system information without checking tens of different programs and files is difficult. It is this problem that Inxi solves. Its a command-line program to get all the detailed system information from the other sources and presents in a convenient format.
$ sudo apt install inxi
$ inxi -b
This displays sections for Machine (brand, product, motherboard and BIOS), CPU, Graphics (GPU, X and graphics driver) and Network (LAN and Wireless cards).
$ inxi -p
$ inxi -r
Reference: Inxi is an amazing tool
Tried with: Inxi 1.9.17 and Ubuntu 14.04
