Q. Linux: Nice looking basic system info
A. Now fastfetch is preferred. If you don't have that use neofetch.
neofetch shows an ASCII logo on the left
and basic system info on the right. Its written in bash so has very
light requirements.

You can also use
$ lsb_release -a
LSB Version: :core-4.1-amd64:core-4.1-noarch
Distributor ID: Fedora
Description: Fedora release 29 (Twenty Nine)
Release: 29
Codename: TwentyNine
And
$ uname -a
