[user@rhel-instance ]$ ls -l var-files.txt

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

To remove a full directory branch, including its contents, we may use the -r option, short for “recursive”:
[user@rhel-instance
]$ rm -r mydir/
[user@rhel-instance
]$ ls -l
total 0
Important Note
Be very careful when using recursive mode to delete things, as there is neither a recovery command for it nor a trash bin to keep files that have been removed in the command line.
Let’s take a look at the review table:

Now that we know how to create and delete directories in a Linux system, let’s start copying and moving content.
Copying and moving
Now, let’s copy some files to play with them using the cp (which stands for copy) command. We may get some powerful awk examples copied to our home directory:
[user@rhel-instance
]$ mkdir myawk
[user@rhel-instance
]$ cp /usr/share/awk/* myawk/
[user@rhel-instance
]$ ls myawk/ | wc -l

To copy more than one file at the same time, we have used globbing with the * sign. This works so that by specifying the files one by one, we can just type * for everything. We can also type the initial characters and then *, so let’s try this by copying some more files using globbing:
[user@rhel-instance
]$ mkdir mysystemd
[user@rhel-instance
]$ cp /usr/share/doc/systemd/* mysystemd/
[user@rhel-instance
]$ cd mysystemd/
[user@rhel-instance mysystemd]$ ls
