Git installation on Ubuntu

Git installation on Ubuntu is pretty simple. If you are looking for git instatlling on the RHEL or Rocky or Oracle Linux you can use this link.

Now most of the software projects are using Git. So let's do installation on Ubuntu wit the following steps:

1. Check for Git exists
2. Install Git
3. Confirm Git Installation

Pre-requisites:

Pick an instance on Cloud or online terminal of Ubuntu 20+ version to this experiment. Here I'm using the KillerCoda provided Ubuntu.

Check for Git exists

This is a common requirement when you join a new project and on the Linux machine you would like to know git installed or not. We have couple of options to check it. Let's do it here:

dpkg -l git

#or

dpkg --list git

In the output first 'ii' in the list means (if there are packages installed, you should see this mark) that the package is correctly installed and available. alternatively you can also try other option to check git installation on Ubuntu.

apt list git

#or

apt list git -a

Or else you can simply use `git` it will works and provides git command help when git already installed.

git

We can see that it is not the latest version as of now, So I wish to get the latest git version on Ubuntu.

Install Git

1. we will download our desired verison of Git tarball, untar it, enter into the extracted directory. 2. Build the source code using make 3. Run the installation using make install

# install pre-requisite libraries 
sudo apt update
sudo apt install make libssl-dev libghc-zlib-dev libcurl4-gnutls-dev libexpat1-dev gettext unzip

# Download your desired version
wget https://mirrors.edge.kernel.org/pub/software/scm/git/git-2.48.1.tar.gz
tar -zxf git-*.tar.gz 

cd git-2.48.1
make prefix=/usr/local all
sudo make prefix=/usr/local install

Now Build steps

Confirm Git Installation

You know already multiple ways ot check git existing on your Ubuntu. Let's quickly validate it with `--version` opton.

git --version

Auomation in mind

Power of your brain should work smart when you look at this instructions any AI tool can gives these but we have God's given our own brain to use :)

#!/bin/bash

SECONDS=0
GIT_VERSION="2.48.1"

if ! sudo apt update; then
    echo "Failed to update package list"
    exit 1
fi

rm -rf git*
sudo apt install -y make libssl-dev libghc-zlib-dev libcurl4-gnutls-dev libexpat1-dev gettext unzip

wget https://mirrors.edge.kernel.org/pub/software/scm/git/git-$GIT_VERSION.tar.gz

tar -zxf git-*.tar.gz 
cd git-$GIT_VERSION
pwd

make prefix=/usr/local all
sudo make prefix=/usr/local install
git --version

  
git --version | grep ${GIT_VERSION}
[ $? -eq 0 ] && echo "Git installed latest version successfully!"
echo "Execution time: $SECONDS seconds"

Magical way of Git installation

The beatiful output of the above bash script is here:
