Using Git and GitHub

We will use GitHub and Git to submit some homeworks.

Full reference on Git is available here.

Installing Git

  1. For Windows users: download and install Git. Run Git Bash.
  2. For Linux users: run command sudo apt install git in Terminal (typically it is already installed).

Generating SSH Keys

Run the ssh-keygen command in the console, to generate SSH keys. Specify the passphrase for the keys. The keys will be generated in the following folders.

  • MacOS: /Users/andrew/.ssh
  • Windows: /c/Users/andrew/.ssh
  • Linux: /home/andrewt/.ssh

id_rsa is a private key, id_rsa.pub is a public key.

Creating Repository

  1. Login into GitHub or create an account.

  2. Add your public SSH key to your account.

  3. Create a new private repository. Name it <group>_<surname>, e.g. 231_tatarnikov. If there is another student with the same surname, add suffix _<n> (n is the first letter of the name).

  4. Add the workshop instructor and the teaching assistant as collaborators to the project. Here is an example of a link to do this (Project > Setting > Manage Access):
    https://github.com/<your account>/<your project>/settings/access.

Working with Repository

  1. Clone the created repository to your machine:

    git clone https://github.com/andrewt0301/test.git

  2. The repository will be cloned in the test folder. Change the current directory to it:

    cd test

  3. See help of using Git:

    git help

  4. Set your user name and email for this repository:

    git config user.name Andrei Tatarnikov
git config user.email andrewt0301@gmail.com

  5. Create or copy the hello.c program to this folder.

  6. Check the status of files in the Git repository:

    git status

  7. Add the hello.c file to the commit:

    git add hello.c

  8. Send the commit to the repository:

    git commit -s -m "hello.c is added"

  9. Update the remote repository (GitHub):

    git push origin main

  10. Get changes from the remote repository (GitHub):

git pull
