Git Tutorial

Version Control

• Allows someone to revisit various version of a file or set of files
• This allows reverting a file or project to a previous version
• Useful for tracking modifications

Local Version Control

A local database on your hard drive

Centralized Version Control

A single server storing all changes and file versions
This allows for programmers to streamline collaboration
gives access to everyone’s files in one spot and gives admins more control

Distributed Version Control

To prevent having a single point of failure ie. the server
DVCS allows mirrored repositories that act as backups
Used to backup lost information

Git

• Git is a DVCS that stores data in a file system made of snapshots
• Commits are saved versions of your project
• Relies on local operations since that is where most necessary information can be found
• Git will track changes which allows it to detect file corruption or loss of info
• Three main stages of Git files
  • Committed - Data is securely stored in a local database
  • Modified - File has been changed but not committed to the database
  • Staged - Flagged a file’s changed version to be committed in the next snapshot
• To clone a repository into your local database use git clone https://github.com/test
• In order to push local changes of your files to GitHub follow A-C-P
  • A- is for git add to track and stage the files first
  • C- is for git commit in order to record what you did and follow it with a -m to explain what and why you made changes
  • P- is for git push origin main to push the changes to the remote repository
