Version Control

is a system that allows you to revisit various versions of a file or set of files by recording changes. Through version control, one can revert a file or project to a previous version, track modifications and modifying individuals, and compare changes. By utilizing a Version Control System (VCS), mistakes with files can easily be rectified.

Git is a DVCS (Distributed Version Control systems) If a CVS goes down, collaborators cannot work with each other on a file or save changes and new versions

git beifitis:

• Git mostly relies on local operations because most necessary information can be found in local resources. This allows for process expediency because a project’s history resides on the local disk, eliminating the need to fetch history information from the server
• very single change applied to any file or directory is tracked by Git.
• Git makes it extremely difficult for a snapshot of your file that is committed to be lost.
• Files in Git can reside in three main states: committed, modified and staged.

1- Committed Data is securely stored in a local database

2- Modified File has been changed but not committed to the database

3- Staged Flagged a file’s changed version to be committed in the next snapshot.

There are three ways to get more information on a particular command, by accessing the manual:

1- git help command

git command --help

man git-command

to import an existing project or directory into Git

$ cd test (cd = change directory)

Use the git init command $ git init

To start tracking these repository files, perform an initial commit by typing the following:

$ git add *.c

$ git add LICENSE

$ git commit -m “any message here”

cloaning

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:

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

## 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.

Committing a File $ git commit -m “made change x,y,z”

Committing All Changes $ git commit -a
