This is a guide for novice on use git tool to practice with a version control system.

git

Git is a software control version system, using logs, you can see all modification (named as commit) of one project.

sudo apt-get install git

First of all, set your user info in your host machine.

• For one local repository, on the actual dir:

  git config user.name "username"
  git config user.email "usermail"
  

• For all repositories on our machine:

  git config --global user.name "username"
  git config --global user.email "usermail"
  

Creating a new repository

There are 2 methods:

• First of them, using github.

  • In github homepage, with your user logged, click on the + button located on left-top of screen.

    

  • Then, choose a repository name y add some description and press Create repository.

    

    If you choose Initialize this repository with a README automatically creates a repository.

  • Then, github shows this screen, with 4 options:

    

    • Create a README, LICENSE and .gitignore files:

      If you click on any of that options, github shows this screen (I choose README).

      

      Then click on commit new file, and now you created your first repository.

      

    • Create a new repository on the command line:

      Create a dir to test git commands:

      mkdir gitTest
      cd gitTest
      

      

      Then, check on your reposiory example and see the changes.

      

    • Import code from another repo, Write the remote repository url:

      

      Click on Begin import and wait a few minutes while is copying the remote repo.

      

      Or click on change repository, this will be clone a remote repository to a new repository (different of example).

      

      Then, check your example repository and see files that were cloned.

      

• Second, create a repository from terminal:

  repo_name="example"
  github_username="Jenazad"
  curl -u $github_username https://api.github.com/user/repos -d "{\"name\":\"$repo_name\"}"
  

  • Next, we init the local repository:

    git init
    git remote add origin "https://github.com/$github_username/$repo_name.git"
    

  • And then, create some file like Readme.md and push it:

    touch Readme.md
    git add .
    git commit -m "readme"
    git push origin master
    

Commands

• Check file status:

  git status
  

• Add files/directories to the local repository:

  git add .
  

• Confirms the uploaded files and set ready to upload to remote from local repository:

  git commit -m "modify"
  

• Push new files to remote repository:

  git push origin master
  

• Pull newest uploaded files from remote to local repository:

  git pull origin master
  

• Configurate a local repository in .git/config add the fields

    [remote "origin"]
        url = https://github.com/path/repo.git
        fetch = +refs/heads/*:refs/remotes/origin/*
