Git

it is a DVCS that stores data in a file system made up of snapshots. multiple developers can work on the same code, it gives you the ability to view, apply and remove files. 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

Every single change applied to any file or directory is tracked by Git. And, as the gatekeeper, Git will always detect file corruption or loss of information in transit

Cloning

it is the creation of a copy of an existing Git repository from a particular server by using the clone command with a repository’s URL.

$ git clone https://github.com/test

Check File Status

To determine the state of files, utilize the git status command:

$ git status

Note that This information indicates which branch you’re on and states “working directory clean,” which means that files have tracked or modified status at the moment.
