Fundamentals 1: Intro to Linux

by Audrey Emis

Linux is an extremely important tool to know as someone involved in computer science. Linux is a very popular free and open source operating system, which means it manages the communication between the software and hardware on your computer. Different machines have different ways of accessing a linux terminal and there are tons of linux commands (along with their options/flags) to cover. We are going through some basic file system traversal using essential linux commands like pwd, cd, and ls. We are also learning how to add and remove files/directories and how to read man pages effectively. There is a lot to learn about the linux operating system and going through OverTheWire's Bandit wargame is a great first step!

Challenges

We are solving levels from OverTheWire: Bandit at overthewire.org/wargames/bandit to learn and practice various fundamental linux commands.

Resources

The following are great resources to learn and practice linux commands.
