At this point in our journey, we've already covered a lot of ground—we've learned
how to deploy an Ubuntu server, how to manage users, and most recently, how to
manage software packages. Before we go too far, we should take a moment to learn
some important concepts and commands that will allow us to build more of the
foundational knowledge that will serve us well for the remainder of the book and
beyond. These foundational concepts include core Linux commands for navigating
the shell, the Linux filesystem layout, viewing the contents of files, and even
checking on log files. Specifically, this discussion will include:
• Learning essential Linux commands
•
Understanding the Linux filesystem layout
•
Viewing the contents of files
•
Viewing application log files
Let's take some time to learn some essential Linux commands that will help
strengthen our command-line skills.
