Most of the users are only interested in having some kind of revision control for their own code. Therefore, we will start with some simple basics, which will allow you to put your code under revision control in a few simple steps and you will also learn how to easily add changes the code. At first you will need to create a repository for your code. To fully grasp what a repository is, you can read the corresponding Wikipedia page, but for now it is sufficient to think of it as a box into which you will put everything that you want to have under revision control. Additionally, the box contains a list, which tracks everything put into the box, everything taken out of it and any changes made to the objects inside.

Creating a new repository

Before we start, please make sure that you fulfill the following conditions:

  • You have some kind of Linux distribution installed
  • You have installed Git
  • You have a folder (we will call it MyFolder), that you want to put under revision control

Once those conditions are met, go into MyFolder and initialize the repository by entering (yellow highlighting used to emphasize output)

user@HPC.NRW:~$ cd MyFolder
user@HPC.NRW:~MyFolder/$
user@HPC.NRW:~MyFolder/$ git ini
Initialized empty Git repository in /home/MyFolder/.git/
