Creating a repository

echo "# sensehat" >> README.md
git init
git add README.md
git commit -m "first commit"
git remote add origin git@github.com:tarikgit/sensehat.git
git push -u origin master
  • Tell GitHub who you are:

git config --global user.email "you@example.com"
git config --global user.name "Your Name"
  • Generate a new SSH key

ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

Press Enter to set a default file location. When asked to Enter passphrase …​, provide a safe password.

  • Add new SSH key to your GitHub account

    • Copy the SSH key to your clipboard

Open id_rsa.pub:

cat ../.ssh/id_rsa.pub
# assuming that the current folder is /home/pi/sensehat

Copy the key and paste it into GitHub

  • Push your first commit

git commit -m "initial commit"
git push origin master
  • Putting all the commands into a sequence:

git add *
git commit  -m "description of commit"
