Git Linux SSH Script

Introduction

In this lab, we set up and used Git, GitHub, and SSH. Outlined here are the steps to install Git on both Linux and Windows, generate personal access tokens on GitHub's developer settings, and use Git commands. We also cloned GitHub repositories, pulled repositories on different computers and lastly created a script to allow for a passwordless SSH login.

Setting Up Git

Installing Git

Ubuntu - apt install git

Centos7 - yum install git

Windows - here

GitHub Configuration

Generating Personal Access Tokens

Go here OR navigate yourself to github.com > Account Settings > Developer Settings > Personal Access Tokens > Tokens (classic)

Generate a token and DO NOT LOSE IT !! (very important)

This will be used as your password when you run the command git push and are prompted to login.

Git Essentials

Basic Git Commands

git add . - adds what you have currently into what WILL be committed then pushed to github

git config user.email - add your github email here

git config user.name - add your github username here. For me that was tmansfield42

git commit -m "input message here" - commits what you added to github with a message, basically gets it ready to be pushed onto official github

git push - You will be prompted to login here. Use the generated token from previous steps. This finalizes the git commit command.

git clone https://github.com/YourRepoHere/ - clones a github repository to your computer.

git pull pulls any new edits to the repository that you have cloned

SSH

Generating RSA Key Pair

ssh-keygen -t rsa -C "sys265"

no password

creating passwordless user

• Copy my secure-ssh.sh bash script

you run this by typing sudo bash secure-ssh.sh
