Hello, and welcome to this course from Pluralsight. My name is
Andrew Mallett, and I'm going to be your instructor as I guide you
through this complete course where we go through and take a look at
CompTIA Linux+: System Management.
Now in this module, we're going to be taking a look and concentrating on
managing Linux files. Now as we go through and take a look,
the whole course is going to help you get up and running with Linux
system administration, as well as DevOps skills.
We're going to be working with different Linux
distributions so you're not just learning one Linux
system. We'll be working with Alma Linux 8.5,
which is a Red Hat 8 rebuild.
We'll be looking at openSUSE 15.2, as well as Ubuntu 20.04.
Within this particular module, we're going to be
taking a look at managing directories, understanding file metadata,
editing files, and copying files both locally and remotely.
Along with that, we'll be taking a quick look at creating SSH
Git repos, but we'll see far more on Git later on as we look at
scripting in another course.
Now one of the important things about CompTIA certification is getting the idea
of you're learning Linux rather than particularly learning one particular
distribution. The recommended systems to work on are as we are working on in
our lab, so Alma Linux, Ubuntu, and openSUSE.
Now for the demonstrations,
we are working with Vagrant and VirtualBox. Now if you can
install VirtualBox and Vagrant on your system,
both are free and available across pretty much all platforms,
you're going to be able to make use of our Vagrant file that can
easily, then build your virtual machines for you. To get into the
main heart of this module though,
we can be taking a look at working at our command line.
Now, of course,
there are some very simple things that we can do, so, of
course, printing our working directory,
moving to a directory using the cd command.
But once we've done that, we actually populate a variable called $OLDPWD.
So we can check the contents of that, and that will be pointing through to our
home directory if that's where we started. That means, then we can actually cd
to that variable or as a shortcut, cd ‑. Now,
of course, looking at this, this just introduces a couple of commands,
the pwd, the cd command,
the echo command and the use of a variable or a shortcut.
Your real skill is by getting good hands‑on experience
through the demonstrations at the command line.
So come on, let's go through and find ourselves a command line environment to work with.
