Basics

This page will introduce the most basic uses of the git version control system

Installing Git

Debian, Ubuntu, and derivatives:

• On modern systems that support the apt command, run apt install -y git as root.

• On older systems that don't support the apt command, run apt-get install -y git as root.

CentOS, RHEL, and derivatives:

If you don't have git installed already, run yum -y install git as root.

Windows:

1. Go to https://git-scm.com/download, and click the Windows icon.

2. Run the installer

Basic Git commands

Clone a repository:

Clone via ssh:

git clone user@host-or-ip:path/to/repository.git

Clone via https:

git clone https://host-or-ip/path/to/repository.git

Pull changes from origin:

git pull

Download file from origin:

git checkout .

Useful if a file is deleted or overwritten by mistake

Add local file to repository

Even if a file is added to your local copy of a repository, it won't be added to the git repo automatically. To add it, you need to run this command.

git add filename.ext

Commit changes

Commit all changes

git commit

Commit changes to specific files:

git commit file0.ext file1.ext file2.ext

Specify commit message in command:

git commit -m "Commit message"

You can combine this with the previous one:

git commit -m "Commit message" file0.ext file1.ext file2.ext

Push local changes to origin:

git push

Changes must be committed for this to go through.
