I started using linux back then in 1998, what I am going to share with you is a relic, but it was my main (and only) reference to learn: The Linux Documentation Project.

It's really really old, but for historical reasons I think you should know about it.

I strongly encourage you to get familiar with man. Man pages are a command line help, as an example, just type man mkdir in a terminal:

MKDIR(1)                      User Commands                      MKDIR(1)

NAME
       mkdir - make directories

SYNOPSIS
       mkdir [OPTION]... DIRECTORY...

DESCRIPTION
       Create the DIRECTORY(ies), if they do not already exist.

       Mandatory  arguments  to  long options are mandatory for short op‐
       tions too.

       -m, --mode=MODE
              set file mode (as in chmod), not a=rwx - umask

       -p, --parents
              no error if existing, make parent directories as needed

       -v, --verbose
              print a message for each created directory

       -Z     set SELinux security context of each created  directory  to
              the default type

       --context[=CTX]
              like  -Z,  or  if  CTX is specified then set the SELinux or
              SMACK security context to CTX

       --help display this help and exit

       --version
              output version information and exit
