Introduction to Operating Systems and Linux Kernel Basics 🐧

Objective: This unit will refresh fundamental OS concepts and introduce the Linux kernel's high-level structure and development environment. The first section is a general very high level review of operating systems in general and the second part covers the Linux operating environment in a medium level of detail with some background and history.

Note: This is the introductory post in what I hope will be a series on the Linux kernel, how it operates and how to use that knowledge to troubleshoot problems. This post is meant as a higher level review that introduces and summarizes the subject. As a summarization some details may be omitted. For a deeper review, see the reading materials section at the end of the document for the source material. I have also placed links to important concepts and terms for easy access throughout the document. As I expand the series I expect to take a much deeper dive into the various parts of the kernel.

StructOpt question

Need to figure out a way to turn mutually exclusive options from StructOpt into someting I can select at runtime. In Python I can do this using argparse and then testing existance on the option something like this:

if args.argument1:
    thing(args.argument1)
else if args.argument2:
    otherthing(args.argument2)

Bash key combinations and shortcuts

The bash shell uses a library called GNU Readline that provides easy and quick CLI key combination access to bash history, screen movement and line editing commands. I've collected some of these here along with some builtin bash shortcuts for history and other functions.

Note: The command bind -p will list all the keybindings and the readline functions they call.
