Learn Bash, Git and Mdx

This workshop will start by breaking down the four states in which a file can exist, and we'll build up our mental model of git from there. Then, we'll look at how to move files between those states in different ways.

Once we've developed a new model for how git operates, we'll be able to purposefully get ourselves into some sticky situations, and then gracefully recover from them.

If you can handle git add/commit/push, but not much more - then this workshop is perfect for you.

You can finally get some proper git training, and will never have to worry about losing data or messing up the repo again!

Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.

Bash is a Unix shell and command language written by Brian Fox for the GNU Project as a free software replacement for the Bourne shell. Bash is a command processor that typically runs in a text window, where the user types commands that cause actions. Bash can also read and execute commands from a file, called a shell script.

Upgrade Your Terminal and Make It a Joy to Work with

“Setting up remote server authentication” will never be on your job description. It’s not one of those desirable responsibilities that convinces talented people to move across the country and pursue the job of their dreams.

But at that dream job, you might be asked to set up an SSH key. You’d better be ready.

In this course, we will learn the fundamentals of creating SSH keys and configuring them for connectivity to a remote server. We’ll figure out how to:

- tunnel SSH connections for easier local debugging
- set up configuration files to simplify the aspect of connecting to remote servers
- use security features like blocking incoming connections

Being prepared is key. Learn the skills now!

SSH for Remote Server Authentication

Extracting meaningful data from strings is a crucial skill when working with bash, and bash gives us powerful tools to do so: `head`, `tail`, `cut`, `sed`, and `awk`. But these tools can be hard to understand without spending time to learn them, so many developers fall into a rut of blindly copying and pasting commands. No more! With this mini-course, you'll understand the basic ins and outs of these commands in under 15 minutes. 


Manipulating strings in bash

SSH provides a secure way for your to [connect to and authenticate with GitHub's servers](https://help.github.com/en/github/authenticating-to-github/about-ssh). While HTTPS connections use usernames and passwords as credentials, SSH instead uses public and private key pairs. These can be generated on your system using a CLI like [`ssh-keygen`](https://help.github.com/en/github/authenticating-to-github/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent) and then associated with your GitHub account using the public key.

In some cases, you may need to connect to more than one GitHub account from the same system. For example, you may have [separate accounts for personal and professional projects](https://ryanharris.dev/managing-ssh-keys-for-github/), which can be difficult to manage manually. Using `ssh-agent` and a SSH configuration file, you can alleviate this pain point by automatically determining which key to use based on your GitHub repository's `git` URL.

Secure GitHub connections with SSH

Knowing your everyday toolset increases your productivity as a developer. And Git is one of those tools you use on a daily basis. Mastering Git is tough; it has hundreds of different commands, often even inconsistent at how you pass in flags and configuration options. On the other side, there are a lot of good Git courses out there already, explaining all of these commands in detail. 

With this course, I aim at a different goal. You will walk through a series of scenarios which you’ll most commonly encounter in your daily work life as a developer. I’m talking:
 - updating your feature branch with the latest changes from master
 - polishing your git history to make it ready for being peer-reviewed
 - moving a set of commits to another branch
 - undoing accidental commits

The goal is not to cover everything, but those tasks that will greatly improve your daily productivity with Git.


Productive Git for Developers

Bash makes automation easy. Just a few lines of code can take care of repetitive tasks for you and your teammates. 

In this course, we’ll dive deep into the automation potential of bash. You’ll learn to leverage common hooks that open up interesting automation possibilities, like git hooks, adding functions and aliases in your bash_profile, and running scheduled jobs in launchd.

For example, we’ll write a git hook that checks package.json for changes, and if there are changes, the hook runs npm install for you automatically. 

Along the way, you’ll also learn:

- more advanced bash commands like exec
- syntax such as redirecting stdout and stderr to the same destination
- timesaving tricks like brace expansions

Automation is all about saving you time — and at only 52 minutes, this course is well worth yours. Enjoy!

Advanced Bash Automation for Web Developers



Humans were never meant to repeat joyless tasks in a precise manner, over and over and over. Computers are meant precisely for these types of tasks.

Bash is a ubiquitous technology in web development that gives you the immense power of automating repetitive tasks you find yourself performing throughout the day.

The topics we cover will give you confidence in creating build scripts that run on continuous integration servers or quickly testing and debugging an API with `curl`. We’ll go over:  - Interacting with the file system - Creating, moving, copying, and deleting files and folders - Finding files and text patterns in files - Creating and running scripts - Language syntax like variables and conditionals.

Automate Daily Development Tasks with Bash

As modern web developers, we are likely to use git on a daily basis. It's a wonderful distributed version control system, and with only a few commands in our toolbelt it is quite powerful and convenient.

In this course, you will learn the basics of using git, as well as some more advanced commands that you should find useful!

How to Contribute to an Open Source Project on GitHub

MDX has grown rapidly since the first commit two and a half years ago. We'd like to celebrate our accomplishments so far, and talk about what lies ahead. We've got lots of plans.
Learn how MDX increases developer productivity, improves educational content authoring, and even peek behind the curtains to see how MDX works.

MDX is an authorable format that lets you seamlessly use JSX in your markdown documents. You can import components, like interactive charts or notifications, and export metadata. This makes writing long-form content with components a blast.

Most projects have automatically generated files or folders from the operating system, applications, package managers etc. Usually, we don't want to include these types of things in our remote repos because they can clutter the git history/storage and are not applicable to everyone that works on the project. In this lesson, we show how to create a `.gitignore` file to ignore files and folders from being tracked by git.

Practical Git: Remove unnecessary git tracking with .gitignore files

When working with Git, the most common thing developers do is stage, commit, and push the changes they make to a code base - this "edit -> stage -> commit -> push" cycle is the main workflow when using Git; it lets developers make "snapshots" of changes to their codebase which they can share and revert back to. In this lesson, we make some changes to our codebase and then `git add` (stage), `git commit` (store in history), and `git push` (sync with our remote repository) those changes. We also use `git status` along the way to see an update of where our repository is at.

Practical Git: Capture code history snapshots with git add/commit/push

`git pull` lets us get the latest changes from our project's remote repo (most likely from co-workers or other developers working on our project) and merge (combine) them with our local code. It's kind of like Dropbox for code, but you tell git when you want it to get the latest changes from the remote when it is most convenient for you. In this lesson, we use `git pull` and discuss how it is a shortcut for running `git fetch` and `git merge`.

Practical Git: Sync local and remote repos with git pull

When working on a project, it is much easier to work on features and bugs in isolation of the rest of the project. We can do this with git branches; a branch is a copy of the working directory, staging area, and project history; we create a branch, then check it out, then add commits. After our feature has been built, we can then merge it back into the main stable branch - which is `master` by default. In this lesson we go over how to create a branch with `git branch {branch-name}`, viewing all branches with `git branch`, switching branches with `git checkout` plus a few helper commands.

Practical Git: Isolate feature development with git branch

Getting started with Git requires you to add a .git folder to your project on your machine and then set up that folder to point to a remote repository. In this lesson, we walk through using `git init` and `git remote` to do this; we use GitHub for this remote repository as an example, but keep in mind that any Git repo hosting service will work.

Practical Git: Create local repos with git init

When working on code, we need a way to stay in sync across multiple devices and potentially multilpe team members. We also may need to work on our code offline. To do these things, we can "clone" a remote repo (from a git repo hosting service like GitHub or Bitbucket); git cloning means we make a copy of an existing remote repository onto our local machine with the `git clone` command. This command also automatically sets up the remote repo and branch tracking. Once our repo is cloned to our machine, we can work on the code in this directory offline or with teammates at the same time and then when we need to sync up we can push our code back to the central “remote" repo; we can also clone this same repo onto multiple machines and “pull” updates from the central “remote" repo whenever we want. In this lesson, we walk through how to do this.

Practical Git: Copy remote repos to local machines with git clone

Sometimes when you run `git merge` (also during a `git pull` which runs a `git merge`) you get a merge "conflict"; this means that the same line(s) of code were changed locally as in new changes in the remote (most likely from another developer working on a related feature); `git merge` can automatically merge all other changes but when the same line is modified in two places, you have to fix the conflict manually. In this lesson, we show how a conflict happening from a `git pull`, and then how to fix it using `git status` to update the conflict markers in our file(s) with conflicts. You can use a graphical app for this, but this lesson will show you how to resolve conflicts directly from the command line and your code editor.

Practical Git: Resolve merge conflicts with git status

Once a feature has been created inside of a branch, we can combine it back into the main `master` branch by using `git merge`. In this lesson, we go through a complete workflow of creating a feature branch and merging it back into the `master` branch.

Practical Git: Sync branches with git merge

Sometimes when we are working we need a way to pause and switch gears to deal with something more critical; often when this happens we aren't ready to create a `git commit`; instead, we can use `git stash` to save our uncommitted changes locally, switch branches and fix the critical issue, switch back to our incomplete feature, and finally run `git stash apply` to get our unfinished changes back into our branch without affecting the rest of the codebase. In this lesson, we show a real world example of doing this with a critical bug.

Practical Git: Save uncommitted changes with git stash

In this lesson we’ll talk about what GitHub is and how to sign up for a GitHub account so you can contribute to an open source project on GitHub.
