Version Control System“A version control system (sometimes called revision control) is a tool that lets you track the history and attribution of your project files over time (stored in a repository), and which helps the developers in the team to work together. Modern version control systems help them work simultaneously, in a non-blocking way, by giving each developer his or her own sandbox, preventing their work in progress from conflicting, and all the while providing a mechanism to merge changes and synchronize work.”
“Mastering Git.”
Version Control System
What is GIT?Git is Distributed Version Control System
“Distributed means that there is no main server and all of the full history of the project is available once you cloned the project”
A Brief History• In 2002, the Linux kernel project bega using a
DVCS calld BitKeeper.• In 2005, the commercial company that
developed BitKeeper broke down, and the tool’s free-of-charge status was revoked.
• This prompted the Linux development community (and in particular Linux Trovalds, the creator of Linux) to develop their own tool - GIT
First of all, definitions • Working tree
A directory in your filesystem that is associated with a repository, containing files & sub-directories• Repository
A collection of commits & branches, saved in the .git directory• Commit
A Snapshot of your working tree at a certain point in time, identified by a revision number.• HEAD
The name for the commit thats currently checked out in.
GIT• 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.

Installing SSH keys on Windows
• To access your Git repositories you will need to create and install SSH keys
• Generating a key pair, ssh-keygen -t rsa• Copy the public key, and paste on gitlab SSH Key
Settings, cat ~/.ssh/id_rsa.pub | clip• Checking your connection, ssh [email protected]
