One year of Ubuntu experience, still not an expert? [closed]

Question

Google always helps to find solution, but most of the time i just copy paste all the codes that are suggested. Sometimes it works like charm, sometimes i screw up my Ubuntu. Not anymore. I really want to know whats under the hood and how these things work. So, please suggest me how to get started from the very basic of Ubuntu, perhaps more generally linux.

Answer 1

Install VirtualBox, set up an Ubuntu guest inside it, checkpoint it, and start experimenting. Restore from the checkpoint if you mess things up too much — after exploring to see why it broke. Best way I know of to learn.

Answer 2

You mentioned the problem.You just copy and paste the commands.You search and find your answers so the command you're finding are needed.Search for them and learn about them.

An alternative solution is man.For sure you know about it.man command will give you valuable information.
