The hexadecimal code you see in front of the master is a unique id that can be used to identify your changes later. For every commit that you commit this unique id is always generated. When you see developer talking, and you hear them saying something about pushing code, it simply means copying your code from your local git the. Now it seems we have a blocker here because we have not talked about this remote stuff.
If there is no remote repository that we can push our code we would have to use flashdrive to copy this code. Well, thanks to company like github. This is the repository. Create a free account with github. Now that you have an account, click on start a project:.

Fill in the next page, type the name you want to name your repo, add description and tick Initialize this repository with a README and click on Create repository. You will be asked to login with your username and password, follow the instruction as it shows on your terminal. If you followed carefully you should have your code on github repo live already. Congratulation you just learnt git, so what next. Like a tree git have branches, these branches let you have a different version of the code in a separate place it is like having different code in different folders and you can switch from one folder to another.
If you enjoyed this post, you might also like:
By default, master is your default branch that is why we git pull origin master the other time. If you want to push to a new branch, you will do. Now you have been working on this your new app for the past few months and last night you added some new features. The new feature is not running afterall. So how do you go back to your previous commit? You can now happily demo your app. Merge conflict usually occurs when different people work on the same file and the changes are not properly synchronized.
To resolve, just compare the two changes, for example in the above code snippet, the person having these conflict changed let to const, but the other person added the moreThings variable, so take out:.
Resolving merge conflict might look simply here, but at times it becomes a decorated demon so be aware! Now that you understood git, you can now start contributing to open source projects. The first step is to fork this repo. To fork a fork just click on the fork button that you see on the repo page. You can either download the zip file and unzip the file or copy the link to the repository, paste it in your terminate and do.
Finally, here are few more commands that you might you need,. To view your uncommitted code, your current branch and other info. After you returned to the branch you did git stash and you want to retrieve your previous work that you stashed, use git stash pop to retrieve them.
The Right Way™
There's no "correct" route. The logical way into tackling a subject to you might be different to someone else. The "see it in action and delve into more details later" approach might not be the way you see the best practitioners developing their skillset, and starting at the theoretical basics and building from there might be the more academically rigorous approach, but it can be effective approach to directing learning.
Shameless plug, I'm the author of Git Evangelism. This is the guide I built to onboard my coworkers during our transition to Git. This guide is updated regularly and differentiates itself by putting the reader in a position to succeed during their first attempt at Git by providing sane defaults which Git does remarkably poorly like setting Sublime Text as the text editor instead of Vim and configuring Beyond Compare as the diff tool and mergetool. GE gives a brief introduction to the commands to move you towards being productive early-on and orders the commands that the user is likely to encounter the need.
I'm going to stop myself here. I could go on a long rant about the awful system defaults.

I have a series of screencasts planned, some recorded, that follow through Git Evangelism so that you, the reader, can use Git confidently and successfully while avoiding the bizarre error states that plague new and seasoned users alike. In addition, I have created a non-traditional in-person workshop event that helps new users build up their understanding of the Git data model and we go in detail on how that differs from a centralized source control system ie.
TFS VC. Git Evangelism is in some ways heavily influenced by the thinking forced by centralized version control systems. The problem with most getting started guides for Git, is that they continue to put the reader in a position to fail rather than a position to succeed. Git has all kind of "gotchas" that guides skip over. A typical guide leads you through staging and committing and reverting but rarely does the guide explain the nuances such as difference between "git add.
Oh wow, I didn't realize you could change git's diff thing. I've never been able to figure out what it was doing, so I always just used a separate gui for diffs.
Initially it took me entirely too long to determine the right config options to launch BC as the diff and merge tool. It's preposterous to be that difficult. A developer should have a default editor he's comfortable with. The defaults are set because of availability. Most systems will have a vim, not Sublime Text. A lot of git tutorials go into detail about how the data model works as part of or even before explaining basic usage. This guide is different in that it explains how to use git in the simplest possible way - conceptually just as a system to make save points - and then covers the data model later after it's shown the merits of the system.
If you need to explain git to someone who has the option of not using it or isn't sold on the whole idea in the first place, this is the absolute best place to start.

They're not being rigorous; it's just simpler to explain in terms of the data model. The data model is very simple and clean and most of git's benefits flow directly from the model. The UI is awful The engineering is brilliant: informative error messages and hints; fast; great features e. The only significant things missing are deliberate design choices inherent in the data model.
It could be simulated with out-of-band info like tags , but isn't.
I can't help but mention Magit  here. Magit is the only thing that makes git usable to me. This webapp definitely helped expand my git knowledge.
