Git Command Guide

Git is a version control software designed by Linus Torvalds, thinking about the efficiency and reliability of maintaining application versions when they have a large number of code files.

Advantages:

✔️ Better teamwork
✔️ Control of changes in the project
✔️ Audit and reliability
✔️ Return to previous versions
✔️ Local & Remotes Repositories
▪️▪️▪️ And much more

About this Guide:

🔈 Everything in bold means that the value is relative, it changes according to each one.
🔈 Is not a finished version.

Star the Project :star:

The easiest way you can contribute is by "starring" this project on GitHub! This will help you to "bookmark" the content so you can return to it. But it will also help the people who "follow" you on GitHub to discover that you find it interesting or useful.

The more people star and share the project, the more possible contributors are able to understand the value of contributing and open sourcing their knowledge!

:octocat: I will be grateful that you follow me :octocat:

Branches

A branch is basically a new timeline that stores commits. They are used to develop functionalities independent of each other. The master branch is the default branch when you create a repository. Create new branches during development and merge them to the main branch when you finish.

Create a branch: 🔱

git branch myBranch

See the branches of our repository: 🔅

git branch

Work in a specific branch 🌿

git checkout myBranch

Create and move to a branch in a single command 🍀

git checkout -b myBranch

Merge branches:

First we go back to the master branch: ❄️

git checkout master

And now we run the next command 🌻

git merge myBranch

Once merged we can proceed to delete the branch 🌹

git branch -d myBranch

Stash

Creation 📦

git stash

Get the list 💼

git stash list

Github

Once we create a repository, we can add it to the remote server: 📮

git remote add origin yourRepo.git

See the remote sources of our repository: ⬛

git remove -v

Once we have all our commits done and we have added the remote repository we can upload our files to Github:

Push: ✈️

git push -u origin master

But, as you can see, the tags are not uploaded with the git push command:

Push the tags ▶️

git push --tags

Ignore Files ❗️

_{For this, you must create a .gitignore files, and there you can write the files and foulders that you dont want to upload to the github repository like:}

node_modules
package-lock.json

Pull 🌌

git pull

Clone a Repository ⌛

git clone repoUrl.git

Clone a repository in a specific folder 📁

git clone repoUrl.git my-folder
