Ubuntu Server Basic Console Commands


Hi, as I’ve mentioned in another article, because of my job as a web developer, I have very little time for posts and videos.

It goes without saying that when I get time I will upload all of my archive I have created from time to time to troubleshoot problems that every company faces in its day to day life, from almost free cloud setup to multiple e-shop automations and more, as well as computerization.

Today, I am giving you my personal Ubuntu Server master command file that I had made for Ubuntu Server in Google Cloud (I will be uploading videos for $ 300 free Virtual Private Server to Google Cloud and how to claim it, setup, settings etc)

Note that some commands may not have the sudo up front, so add it or get admin rights with sudo su – on the console to prevent it from being used.
