How to setup ruby development setup in Ubuntu 20.04
setup git and github
You can create an account https://github.com/ with your email
And then setup git with the same account that we used with github.
Please replace DEVELOPER_NAME with your name and DEVELOPER_EMAIL with your email address
in below commands
# install git module
sudo apt-get update
sudo apt-get install git-core
# Configure git
DEVELOPER_NAME="rakesh"
DEVELOPER_EMAIL="rakesh@tenderprog.com"
git config --global color.ui true
git config --global user.name $DEVELOPER_NAME
git config --global user.email $DEVELOPER_EMAIL
# generate ssh key
ssh-keygen -t rsa -b 4096 -C $DEVELOPER_EMAIL
Next we need to add SSH key to your github account “settings” -> “SSH and GPG keys” here https://github.com/settings/ssh
and add “New SSH key”
Once you are done with above mentioned steps
run below command to verify the setup
ssh -T git@github.com
# you should see a message similar to below, that indicate setup is completed
Hi YourGithubAccountName! You've successfully authenticated, but GitHub does not provide shell access.
