Hello and welcome,
It sounds like you already understand the basics like concepts of ‘terminal’ and ‘command’.
After that a great first step is getting familiar with -h, --help and man.
With these you should be able to navigate an understanding of how most things work.
In a moment I’m going to ask for the output of an inxi command.
First you can take a look at how inxi works using any of the following;
inxi -h
inxi --help
man inxi
(this final man command will overtake the terminal window and you can exit using Q)
While not all terminal utilities will have --help flag or a man page … they will usually have at least one of the above methods of providing information on how to use them.
Please run the following and copy its output here:
inxi -Farz
