It has been four months since I have started my technical journey once again and I have decided to focus my attention on the key cloud platforms of today. My first remark is that regardless of the tech I play with or certification I follow, I would have to go through some UNIX commands and CLI and to try to figure out some obnoxious file ownership, firewall or environment variables – and without knowing about these there are no chance you will do anything.
So I had to have a look at Linux in depth again. I remember in 2007 at University used it quite a lot, and for me it was weird to log in again, it seemed so familiar yet so distant. Clearly, I did obviously forgot most of it apart from the very basic commands.
I followed the course from Dion Training, available on Udemy and went through this book , I eventually got Linux+ certified from CompTIA, It took me a month and a half with an average of 2 hours per day to succeed at it. It is impressive to see the industry seeing it as the absolute requisite to almost anything nowadays, back then in 2000 something, it wasn’t such a huge phenomenon.
