How to set important Git configuration global properties

There are many ways to customize a development environment, but the global Git configuration file is one that is most likely to be used for custom settings such as usernames, emails, preferred text editors, and remote branches. Here are the key things you need to know about global Git configuration files.

How to set important Git configuration global properties

Where is the global git configuration file located?

The global Git configuration file is stored in a home directory called .gitconfig user. Depending on the operating system, this will be:

  • C:Users on Windows
  • ~home/Linux
  • ~root/ for sudo operation

One thing to note is that each user has his own global Git configuration file. This can cause problems if you run a shell script using the sudo command. If you use sudo in your script, the ~root/.gitconfig file will be used instead of the global git configuration file of the user running the script. This can lead to unexpected results, so use the sudo command with caution.

show git config global

The git config –list command will display global git configuration settings.

Git configures global username and email

Before issuing a local Git submission, you must set the global git configuration username and email properties. Don't worry, your name and email won't appear on the mailing list. These details are used only as metadata in each commit, so anyone who looks at the Git logs will know who submitted the code and how to contact them. There is nothing evil about the global username and email requirements configured by Git.

How to set global git configuration settings?

There are several ways to edit a global git configuration file. One way is to add properties via the command line. Global git configuration email and username properties are usually set as follows:

 git config --global user.name cameraonmcnz
git config --global user.email global-config@example.com 

For more expressiveness, you can include the –add switch when setting the global git configuration properties:

 git config --global --add user.name cameraonmcnz
git config --global --add user.email global-config@example.com 

How to perform git config global editing?

The global git configuration is just a text file, so it can be edited using any text editor of your choice. Open, edit the global git configuration, save and close, and the changes will take effect the next time the git command is issued. It's that simple.

From a BASH shell or terminal window, you can call the default Git editor with the following command:

 git config --global --edit 

On Ubuntu, this will open the Nano text editor, which I don't really like. Fortunately, the global git configuration file can be used to change the default Git editor to what you think is more user-friendly.

Configure Git global core editor

The following commands can be used to change the default text editor for global Git configuration to Vim, emacs, Textmate, or Atom. There is a separate tutorial on how to make the core editor for NotePad Git, which is easy to do on Windows, but a little hard to predict on Linux.

Global Git Config Core Editor Settings
Text Editor Global Git Config Command
Atom git config –global core.editor “atom –wait”
emacs git config –global core.editor “emacs”
Textmate git config –global core.editor “mate -w”
vim git config –global core.editor “vim”

How to override Git global configuration?

Git uses the gitconfig file's cascading application to determine the value of the Git configuration properties used at runtime. Here are five common Git configuration ranges, from the most specific to the most general:

  1. workingtree
  2. local
  3. Global
  4. system
  5. portable

Since the working tree and local git scope are more specific than global, any variables set in these files will override the git config global scope. So if you need a specific Git configuration username or email for a given repository, or a special setting for the Git work tree you want to add, you can use local or work tree scopes.

List and display global git configuration

To view all properties of the global configuration in Git, you can use the --list switch on the git config command. Adding the --show-origin switch will also tell you where the global .gitconfig file is located.

 global@git:~/$ git config --global --list --show-originfile:/home/gme/.gitconfig user.email=cameronmcnz@example.comfile:/home/gme/.gitconfig user.name=cameronmcnzfile:/home/gme/.gitconfig core.editor=vimfile:/home/gme/.gitconfig http.sslverify=falsefile:/home/gme/.gitconfig credential.helper=storefile:/home/gme/.gitconfig http.proxy=193.168.0.11file:/home/gme/.gitconfig http.postbuffer=193.168.0.12file:/home/gme/.gitconfig http.sslcainfo=193.168.0.10 

Delete global git configuration settings

To remove the git configuration settings, simply use the unset command:

 git config --global --unset core.editor 

Sometimes, a property is set twice and the –unset switch fails. In this case, just use the --unset-all switch of the global git config.

 git config --global --unset-all core.editor 

Global git configuration is an important file for custom version control experience. It is important to know how to display Git configuration settings, and it is also important to be able to edit, update, and delete settings. Knowing how to do it will surely make your experience with the global Git configuration tool even more enjoyable.

How to use PHP to build social sharing functions PHP sharing interface integration practice How to use PHP to build social sharing functions PHP sharing interface integration practice Jul 25, 2025 pm 08:51 PM

The core method of building social sharing functions in PHP is to dynamically generate sharing links that meet the requirements of each platform. 1. First get the current page or specified URL and article information; 2. Use urlencode to encode the parameters; 3. Splice and generate sharing links according to the protocols of each platform; 4. Display links on the front end for users to click and share; 5. Dynamically generate OG tags on the page to optimize sharing content display; 6. Be sure to escape user input to prevent XSS attacks. This method does not require complex authentication, has low maintenance costs, and is suitable for most content sharing needs.

There are three main ways to set environment variables in PHP: 1. Global configuration through php.ini; 2. Passed through a web server (such as SetEnv of Apache or fastcgi_param of Nginx); 3. Use putenv() function in PHP scripts. Among them, php.ini is suitable for global and infrequently changing configurations, web server configuration is suitable for scenarios that need to be isolated, and putenv() is suitable for temporary variables. Persistence policies include configuration files (such as php.ini or web server configuration), .env files are loaded with dotenv library, and dynamic injection of variables in CI/CD processes. Security management sensitive information should be avoided hard-coded, and it is recommended to use.en

To enable PHP containers to support automatic construction, the core lies in configuring the continuous integration (CI) process. 1. Use Dockerfile to define the PHP environment, including basic image, extension installation, dependency management and permission settings; 2. Configure CI/CD tools such as GitLabCI, and define the build, test and deployment stages through the .gitlab-ci.yml file to achieve automatic construction, testing and deployment; 3. Integrate test frameworks such as PHPUnit to ensure that tests are automatically run after code changes; 4. Use automated deployment strategies such as Kubernetes to define deployment configuration through the deployment.yaml file; 5. Optimize Dockerfile and adopt multi-stage construction
