What is Linux ?
Linux is an open source operating system . An operating
system is the software that directly manages a system's
hardware and resources, like CPU, memory, and storage.
The OS sits between applications and hardware and makes

What is git?
● Open source project originally developed in 2005 by
Linus Torvalds
● A command line utility
● You can imagine git as something that sits on top of
your file system and manipulates files.
● A distributed version control system - DCVS

What is “distributed version
control system” ?
● Version control system is a system that records
changes to a file or set of files over time so that you can
recall specific versions later
● Distributed means that there is no main server and all
of the full history of the project is available once you
cloned the project.

● You can imagine git as something that sits on top of
your file system and manipulates files.
● This “something” is a tree structure where each commit
creates a new node in that tree.
● Nearly all git commands actually
serve to navigate on this tree and
to manipulate it accordingly.
git
branch
commit

Github
● GitHub is a web-based Git repository hosting service

The three steps of git
Add the change to
staging area
Make that change
“permanent”
git add
git commit
● Introduce a change: introduce a change to a file that is
being tracked by git
● Add the actual change to staging area: Add the
change you actually want using “git add”
● Commit: Commit the change that has been added using
git commit
Introduce changes

git commands
● For most of the basic interactions with git you’ll mainly
use 7 commands that we’ll cover here

git commands
● git init
● git clone
● git log
● git diff
● git status
● git add
● git commit

git init
● Creates a new git repository
● Can be used to convert an existing, unversioned project
to a git repository or initialize a new empty repository

git clone
● Copies an existing git repository

git add
● Adds changes
Introduce a change
Add the change to
staging area
Make that change
“permanent”
git add
git commit

git commit
● Creates a commit out of the changes that had been
added
Introduce a change
Add the change to
staging area
Make that change
“permanent”
git add
git commit

git diff
● Displays the change that was introduced
Useful flag:
● --cached:
Displays the change that was added using “git add”

git status
● Displays the file names that has been modified, added
and untracked
