Introduction

A few things I can recall about using Linux Ubuntu flavour...

• ssh root@xx.xx.xx.xx/password:, (this is how you secure shell into a remote server using either Windows MS DOS Command Prompt/or, Windows Powershell

• logout, (how you logout of a SSH session)

• apt update && apt upgrade, (this command will both update/upgrade all software packages)

• hostnamectl set-hostname yourSelectedHostname, (changes the Linux prompt text)

• usermod -aG sudo username, (sets up username with sudo privileges...meaning, you no longer have to log in as 'root')

Programming languages already built-in...

• Bash

• How to install other programming languages...

• apt install ruby

• apt install python/apt install pip

• apt install julia

NOTE: Compared with other operating systems such as, Microsoft Windows...; It is almost unbelievably quick and simple to find/install/run programming languages/code. I think, because Linux -which is written in C- is based off of the Unix operating system...; and, Unix was written by programmers for programmers...; therefore, using Unix/Linux is like finding sheer programmers heaven...there is just loads and loads to discover in terms of programming languages you can find/play around with using.
