# Hello ! 
# This is a simple/minimal script 
# To fetch some basic information about your system
# I made this for my own personal use 
# It is limited as you can see
# It's my own take on neofetch but less flashy and less fancy lol
# I understand that my code isn't 5* quality ,so yeah ...
# I only tested it on Kali and Ubuntu 
# On other distros some commands won't work
# So please feel free to change whatever command
# Does not work with the appropriate one for your system .
