What is git config global?

Git (an acronym of Global Information Tracker) is a distributed version control system that is used to store files/code and then the content can be accessed either locally or remotely. It facilitates the programmers to work in parallel manner and as it tracks the recent changes made in the code and the developers can fall back to the previous versions also. The Git repositories are managed by GitHub; GitHub is cloud based service dedicated to providing extended functionalities of Git and to control its repositories. Although it is noticed that Git is widely used for handling source code, it is also being used for several other purposes like human resource departments, marketing organizations, customer support providence. Once the Git repository is set, one can edit the configuration settings by using Git Config command; For instance, if you have set a local repository Git, you may require adding username, email by issuing the Git Config.
