What is Git?

Git is a software that allows people to keep track of changes made to a project over time.

• This works by recording changes they make to a project, stores changes, then allows them to reference them as needed

git init  - init meaning initialize, command setting up all the tools Git needs to being tracking changes made to the project.

 

Git Workflow can be said to have 3 parts 

 

1. Working Directory → where it does all the work : creating, editing, deleting and organizing files 
2. Staging Area → list changes made to the working directory 
3. Repository → where git permanently stores changes as different versions of the project 

Workflow : 

 

1. Edit files in the working directory
2. Adding files to the staging area
3. Saving changes to a Git repository 

Save changes with a commit

Basics of how it works

git status = checking status of the changes of the contents

Untracked = Git sees the file but has not started tracking changes

→ git add = add file for git to start tracking it

→ git diff = check differences between the working directory and the staging area 

→ git commit = last step in git workflow 

• Commit permanently stores changes from the staging area inside the repository 
• Need the -m before the message

  

• Must be quotation marks
• Written in the present tense
• Should be brief 

→ git log = refer back to an earlier version of a project - commits are stored chronologically in the repository and can be viewed with log

In summary

Git is a tool used for source code management. It is free and open-source version control system and it can handle large projects efficiently. Using git and github should be one of the basics that DevOps should be learning.
