Git Command Guide



git-germancutraro


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:

  • โœ”๏ธ Better teamwork
  • โœ”๏ธ Control of changes in the project
  • โœ”๏ธ Audit and reliability
  • โœ”๏ธ Return to previous versions
  • โœ”๏ธ Local & Remotes Repositories
  • โ–ช๏ธโ–ช๏ธโ–ช๏ธ And much more

Download
Linux Debian: $ sudo apt-get install git
Linux Fedora: $ sudo yum install git
Mac
Windows
You can write the commands in your CMD or in the git bash terminal

About this Guide:

  • ๐Ÿ”ˆ Everything in bold means that the value is relative, it changes according to each one.
  • ๐Ÿ”ˆ Is not a finished version.

Star the Project โญ

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:
