Git is the most popular Software version control system used to track changes in source code during software development. Also, It allows programmers to collaborate, revert to previous changes and create branches.
In this context, we shall look into how to install Git on Debian system.
Different methods of Installing Git on Debian
Before performing this installation procedure, ensure that you are using a user with sudo privileges.
To install Git on Debian, we can use any of the given methods:
- Installing Git on Debian with Apt.
- Installing Git from a Source.
1. Install Git on Debian with Apt
Git is available at Debian default apt repository so we will install from there. It’s always recommended to install packages from Debian default repository.
i. So first of all we need to update apt package manager index using below command:
$ sudo apt update
ii. Once the list is updated execute the below command to install Git:
$ sudo apt install git
iii. You can verify the installation by typing:
$ git --version
It will show output like below:
git version 2.11.0
That's all. You have successfully installed Git version on you Debian system.
2. Installing Git from a Source
Another installation method is to compile the software from source. It will allow you to download the latest release and to do customization. But you can't manage Git package from apt package manager.
i. Before you start, you need to install necessary software which Git required. These all are available from default Debian repository. Execute below commands:
$ sudo apt update
$ sudo apt install make libssl-dev libghc-zlib-dev libcurl4-gnutls-dev libexpat1-dev gettext unzip
ii. After that, you can go ahead and get the version of Git you want by visiting the Git project's mirror on GitHub https://github.com/git/git/releases and copy the latest release link address that ends in .zip
iii. Now we will download Git source to /tmp directory on your Debian system. Move to /tmp directory by typing:
$ cd /tmp
iv. Use the wget command to download the archive file as git.zip:
$ sudo wget https://github.com/git/git/archive/v2.21.0.zip -O git.zip
v. Once download is finished, unzip the downloaded file and move to the git source directory by typing:
$ unzip git.zip
$ cd git-*
vi. Now, you can compile and install Git by typing these two commands:
$ sudo make prefix=/usr/local all
$ sudo make prefix=/usr/local install
vii. Again, you can verify installation by typing:
$ git --version
It should show installed version of Git as given below:
git version 2.21.0
Later, if you have need to upgrade to a newer version, you can repeat the installation process.
How to Set up Up Git ?
Now your Git is installed and you need to configure it by setting up email address and username:
$ git config --global user.name "Admin"
$ git config --global user.email "email@example.com"
You can see entered details by typing:
$ git config --list
These settings are stored at ~/.gitconfig file and you can see content as below:
name = Admin
email = firstname.lastname@example.org
You can make other git configuration changes by using git config command or you can edit the ~/.gitconfig file manually.
How to Uninstall Git from Debian Linux System ?
To remove just git package itself from your system, execute the command below on terminal:
$ sudo apt-get remove git
To remove the git package and any other dependent package which are no longer needed from system Trusty, run the following command:
$ sudo apt-get remove --auto-remove git
If you also want to delete configuration and/or data files of git from Ubuntu Trusty then this will work, run the command:
