[Technical Post] Detailed explanation of GitHub installation directory

GitHub is a hosting platform for open source and private software projects. When using GitHub, the installation directory is a more important issue.
The installation directory contains the local location where Github is installed. It not only determines the path of Github, but also affects some configuration and use of Github.

This article will introduce you to the GitHub installation directory, including the installation path, directory structure, and necessary configurations and precautions.

1. GitHub installation path

GitHub can be installed on Windows, macOS and Linux. The installation paths of different operating systems are different.

1. Windows operating system

On the Windows operating system, just download the GitHub installation file (.exe), double-click to run it, and the system will automatically install the software program to C:\Users\username\AppData\Local\GitHub\PortableGit_XXXXXXXXXX (ten X represents the installation date) directory.

2. macOS operating system

When you install GitHub Desktop for Mac, GitHub will be installed into your Applications folder by default.

3. Linux operating system

On the Linux operating system, you can use the command line or directly download the installation file for installation. For various Linux installation paths, please refer to the official help document .

2. The structure of the GitHub installation directory

The GitHub installation directory includes the following subdirectories by default:

1. bin: Contains Git and some command line tools.
2. etc: Contains Git configuration files and SSH files.
3. libexec: Contains utilities for Git.
4. share: Contains some shared Git projects.
5. ssl: Contains Git’s SSL certificate.
6. tmp: Contains temporary files.
7. usr: Contains libraries used by Git.

The role of these subdirectories is very important, so special attention must be paid when operating.

3. Necessary configurations and precautions

When installing GitHub, you need to pay attention to several necessary configurations and precautions:

1. Make sure that Git is installed correctly .
2. GitHub's configuration files are stored in the etc directory, including username, email and SSH.
3. When using GitHub, you can configure Git's global user name and email. You can use the following command to configure it:

$ git config --global user.name "Your Name"
$ git config --global user.email "your.email@example.com"

4. When using GitHub, you need to configure SSH to ensure communication between GitHub and Git. You can refer to the official GitHub help document for detailed steps on how to generate an SSH key and add a public key to GitHub.

In short, the installation directory is the basis for software operation, and different paths will affect the configuration and use of GitHub.
