Introduce yourself to Linux with Oracle Always Free Account

Things have changed for me personally since the last post I shared with you. Work focus has shifted due to a change in project and I know find myself working on a lift and shift to cloud project where i’m also writing some backend stuff.

(As an early preview the next post i’ll write will be around Data Obfuscation…)

Off the back of this I have been forunate to have my first exposure to linux and personally it’s brilliant. From my own personal journey into IT it has been a fascinating insight and I feel as though its opened a huge door that i’m ready to explore. What i’m writing about here is the Oracle Always Free instance of a linux machine i’ve spun up to act as a playground.

Creating the instance can take less then 5 minutes…

Following the link above, I put together my own instance. Some reading about the generating a putty-key and I was away to explore my way round a linux machine. More details below:

Highlights of my learning so far…

vi – vi, for those who don’t know, is a command you can execute that’ll allow you to edit a document within linux. Further to this, there’s another list of navigation commands through the keyboard setup for you to quickly manipulate the information in the file. Just copy and paste into text editor you say? It’s a quick to learn skill that’s rewarding to feel competent at.

pwd – moving over to navigating solely from the command line did take a few hours to get used to, but the best piece of advice I was given by a senior colleague was to check your present working directory – pwd.

These humble three key strokes have been crucial, you know where you’re operating from and have the security to write out your next command.

Finally, this is all well and good. But why would you learn to use linux machines? Personally, its captured my interest, but that isn’t enough for everyone. Take a look at these stats and you’ll struggle to argue that the knowledge gained on an OCI always free linux instance wont be a positive.

amazing….

I plan to be back soon with some stuff around data masking and more OCI linux tales, probably a deeper dive into the learning of using Oracle on Linux….
