Git

Git is a DVCS that stores data in a file system made up of snapshots. Each time you save a changed version of your project — called commit — Git creates a snapshot of the file and stores a reference to it. If the file has not changed, Git only stores a reference to the already-stored identical version of it.

Files in Git can reside in three main states: committed, modified, and staged.

• Committed Data is securely stored in a local database
• Modified The file has been changed but not committed to the database
• Staged Flagged a file’s changed version to be committed in the next snapshot

Setting up a Git Repository

• Importing : 1- Switch to the target project’s directory. 2- Use the git init command. 3- To start tracking these repository files, perform an initial commit.

• Cloning : You can also create a copy of an existing Git repository from a particular server by using the clone command with a repository’s URL.

Local Repository Structure

The local Git repository has three components:

1- Working Directory: The actual files reside here. 2- Index: The area used for staging. 3- Head: Points to the most recent commit.

.

The Life Cycle of File Status:

1- After you edit a file, Git flags it as modified because of changes made after the previous commit. 2- You stage the modified file. 3- Then, you commit staged changes.

Some of the commandes to use :

1- Check File Status: you can do that by using the command (git status).

2- Tracking and Staging a Newfile :

• single file: you can do that by using the command (git add file name).
• all files: you can do that by using the command (git add *).

3- Committing a file: you can do that by using the command (git commit -m “why are you making a change”).

4- Pushing changes: you can do that by using the command (git push origin main).

Those are some of the features existing in Git.
