Now that MongoDB has been installed on your system, let's run a quick test to ensure everything is working properly.

Access a command line via your terminal program and execute the following command:

    $ mongod --version
    db version v3.4.4
    $ mongo --version
    MongoDB shell version v3.4.4  

Assuming that your MongoDB installation was successful, you should see the version number that was installed as an output on the screen, right under the command you executed.
