4. Linux History
Before we start, watch:
https://www.youtube.com/watch?v=xfBWk4nw440&list=WL&index=186
Linux is an operating system (OS)
Open source and inspired by UNIX, a commercial OS started at AT&T
Linux kernel is core part, started by Linux Torvalds, now many developers
Originally ran on 386 processor or better PCs

5. Linux Overview
Besides the Linux kernel is core part, the whole system, also called Linux
includes lots of other software, and comes in different versions called
distributions.
We will focus on Fedora which is a free distribution by RedHat.
The first time I installed Linux, it was SlackWare distribution on 52
individual 3.5” floppy disks

6. Command Line
Before graphical user interfaces, GUIs, existed, everything was command
line interface, which is text based. Harder to learn, but lets you automate
things easily.
Some basic commands: man, info, ls, cd, pwd, mkdir, cat, less, cp, mv, rm

7. Editors
Some popular Linux editors that you can use from the command line are
nano, vim, and emacs. For very beginners, I recommend nano.
● vim (VI Improved), https://www.tutorialspoint.com/vim/index.htm
● emacs, http://www.jesshamrick.com/2012/09/10/absolute-beginners-

nano-the-linux-command-line-text-editor/

8. Installing Software
Linux software is usually installed using a package manager in units called
packages
This varies by distribution.
RedHat based distributions like Fedora use RPMs (RedHat Package Manager)
But modern version uses a higher level program on top of rpm, called dnf
(docs), previously called yum, (wikipedia entry)
We aren’t going to worry about this much for now.
