Revisions and the Cloud

Version Control

Version Control is a system that lets you save and revisit different versions of a file or project. A Version Control System (VCS) helps you go back to earlier versions, see what changed, who changed it, compare updates, and fix mistakes easily.

Cloning

Cloning in Git means making a copy of an existing Git repository from a server. You do this using the git clone command and the repository’s URL.

When you clone a repo:

All versions of all files are copied
A new directory is created
A .git folder is added
Git checks out the newest version of the project

Example command:

git clone https://github.com/test

Commands to track and stage files

The linux command used to track and stage files is git add.

To stage a single file:

git add "filename"

To stage all files:

git add .

Take a snapshot of your changed files

Saving your changes in Git is called a commit, and Git creates a snapshot of your project when you commit.

Commit staged changes with a message:

git commit -m "any message here"

Example with details:

git commit -m "made change x,y,z"

Commit all modified tracked files:

git commit -a

Sending changed files to Github

To send your changes to a remote repository, referred to as “pushing changes”, use:

git push origin master

This pushes your changes from the local master branch to the remote repository named origin. When you clone a repo, Git automatically names the original server origin.
