Basic Git commands

There are many commands that you can use with Git, but some of the most commonly used ones include the following:

  • git config: This is the command used to configure your local Git environment. The configuration can be global; the values will then be kept in your home directory in the .gitconfig file. The values can only be set per repository, and then they will be kept within the repository.
  • git init: This initializes a new Git repository. When you run this command in a directory, it creates a new .git directory in the root of the project, which is used to track changes made to the project’s files.
  • git clone: This creates a local copy of a remote Git repository. When you run this command, it creates a new directory with the same name as the repository and clones all of the files and their history into that directory.
  • git add: This stages files for commit. When you make changes to a file in a Git repository, those changes are not automatically...
