However, if many files are in the archive, a better invocation (to easily read or
scroll through the output) is this:

To expand the contents of a compressed archive, use tar’s zxf options, as
follows:

The tar utility decompresses the specified archive and extracts the contents
in the current directory.
Using Multiple Terminals with byobu
Many Linux veterans have enjoyed and use the GNU screen command,
which was designed to enable you to use one terminal to control several
terminal sessions easily (see https://www.gnu.org/software/screen/ for more
info). Although screen has been and is a welcome and useful tool, you
should consider byobu, which is an enhanced version of screen. Byobu is
a Japanese term for decorative, multipanel, vertically folding screens that are
often used as room dividers.
Picture this scene: You connect to a server via Secure Shell (SSH) and are
working at the remote shell. You need to open another shell window so you
can have the two running side-by-side; perhaps you want the output from top
in one window while you’re typing in another. What do you do? Most people
would open another SSH connection, but that is both wasteful and
unnecessary. Like screen, byobu is a terminal multiplexer, which is a
fancy term for a program that enables you to run multiple terminals inside one
terminal.
The best way to learn byobu is to try it yourself. So, open a console, type
byobu, and then press Enter. Your display blinks momentarily and is then
replaced with a new console with new information in a panel at the bottom.
Now do something with that terminal: Run top and leave it running for the
time being. Press F2. Your prompt clears again, leaving you able to type. Run
the uptime command.
Pop quiz: What happened to the old terminal running top? It is still running,
of course. You can press F3 to return to it. Press F4 to go back to your
uptime terminal. While you are viewing other terminals, the commands in
