In a freshly installed Ubuntu system you may find that Git is not installed. You can check for the Git version on your machine by entering the following in a terminal:
$ git --version
If Git is installed the terminal response will look like:
git version 2.25.1
otherwise the response will be:
Command 'git' not found, but can be installed with:
sudo apt install git
Git installation and basic configuration
Step 1. Install Git
1. Open a terminal.
2. Update apt index:
$ sudo apt update
3. Install Git with apt:
$ sudo apt install git
4. Verify installation is successful by checking Git version:
$ git --version
The response should be similar to:
git version 2.25.1
Step 2. Configure Git
1. Globally configure your username and email:
$ git config --global user.name "John Doe"
$ git config --global user.email johndoe@example.com
2. Globally configure editor (e.g. nano) used by Git:
$ git config --global core.editor nano
3. If your machine is working behind a corporate proxy then globally configure the proxy:
$ git config --global http.proxy http://yourProxyUsername:yourProxyPassword@yourProxyDomain:port
4. Finally, check your Git configuration:
$ git config --list --show-origin
Your git configurations are stored in a .gitconfig file located in your home directory i.e. ~/.gitconfig
