Configure your environment

Install

• Windows - Install 'Git for Windows' from Git for Windows.

• Mac

  • Type 'git' in the Terminal application.
  • If it's not installed, it prompts you to install it.

• GNU/Linux - Enter which git in the Terminal application and press Enter to determine if Git is installed on your system.

  • If the output of that command gives you the path to the Git executable, similar to /usr/bin/git, then Git is already installed on your system.
  • If the output of the command displays "command not found" error, Git isn't installed on your system.

  GitLab recommends installing Git with the default package manager of your distribution. The following commands install Git on various GNU/Linux distributions using their default package managers. After you run the command corresponding to your distribution and complete the installation process, Git should be available on your system:

  • Arch Linux and its derivatives - sudo pacman -S git
  • Fedora, RHEL, and CentOS - For the yum package manager run sudo yum install git-all, and for the dnf package manager run sudo dnf install git.
  • Debian/Ubuntu and their derivatives - sudo apt-get install git
  • Gentoo - sudo emerge --ask --verbose dev-vcs/git
  • openSUSE - sudo zypper install git

• FreeBSD - sudo pkg install git

• OpenBSD - doas pkg_add git
