What should a linux user know?

Question

linux

Hello. I've been using ubuntu for over a year now, but I don't seem to know much, although I've run into a lot of problems. So, I wanted to ask what an advanced linux user should know?

I want to know a lot about linux, because I want to become a programmer and write software for this system.

Answer 1

The most important knowledge of a Linux user is to know how to correctly formulate a question for a search engine and a forum. If you do not know this and do not know how, then you will never get the rest of the knowledge.

Answer 2

For advanced user knowledge, we recommend reading the book "Linux Internals" by Brian Ward -

The database administrator must be familiar with the DBMS.
The programmer must know... How to build crutches to crutches.
