Listing, creating, copying, and moving files and directories, links, and hard links

It is important to know how to manage files and directories (also known as folders) in a system from the command line. It will serve as a basis for managing and copying important data such as configuration files or data files.

Let's start by creating a directory to keep some working files. We can do so by running mkdir, short for make directory:

[user@rhel8 ~]$ mkdir mydir
[user@rhel8 ~]$ ls -l

[user@rhel8 ~]$ ls -l
total 0
drwxrwxr-x. 2 user user 6 Dec 23 19:53 mydir
[user@rhel8 ~]$ mkdir deleteme
[user@rhel8 ~]$ ls -l
total 0
drwxrwxr-x. 2 user user 6 Dec 23 20:15 deleteme
drwxrwxr-x. 2 user user 6 Dec 23 19:53 mydir
[user@rhel8 ~]$ rmdir deleteme
[user@rhel8 ~]$ ls -l
total 0
drwxrwxr-x. 2 user user 6 Dec 23 19:53 mydir

However, rmdir...
