echo %PATH%

3. If Git is installed properly, the output will include your Git installation path. If you do not see this path in the output, then Git is not installed properly or PATH variable is not set properly.

If you get an error message when you try to run any Git command, it may indicate that Git was not installed properly or PATH variable is not set properly.

The third step to verify the Git installation is by creating a new repository.

To create a new repository using Git, follow these steps:

1. Open the Command Prompt.
2. Create a new directory by using the following command:

mkdir new-git-repo

3. Change the current directory to the new directory created by the following command:

cd new-git-repo

4. Initialize the Git repository:

git init

If this process completes without any errors, then Git is installed properly on your system.

Lastly, Git comes with a set of built-in tests that you can run to ensure that all of its features are working properly. As a user, you can run these tests by using the following command:

git --exec-path=/usr/share/git-core/ --html-path=/usr/share/doc/git-doc/ git-cvsweb --test

If there are any issues with the output of these tests, it means that Git has not been installed properly.

With the help of these quick and easy steps, you can easily verify if Git is installed properly on your system. Verifying the installation process and functionality of the Git is an important part of the Git installation process, allowing users to work with ease and avoid any issues later on.
