Neofetch
Add a little bit of fun to your Terminal window with Neofetch - and helpful information about the machine you’re working on.
I installed using homebrew on my mac using..
brew install neofetch
On the Raspberry Pi
Sudo apt-get install neofetch
The program has no other use than snapshoting the system information you want so see or send to another person.
As a sysadmin or covering multiple sites/servers its a great tool to quickly see the machines specs.
