Git is a powerful version control system that makes it easy to track changes to your code. It is also important to keep track of your project’s files and folders, and to ensure that only the necessary files are stored in the repository. One way to do this is to use a .gitignore file. A .gitignore file is a plain text file that specifies which files and folders should not be tracked by Git. In this article, we will explain how to add a .gitignore file to a repo.
What is a .gitignore File?
A .gitignore file is a plain text file that contains a list of files and directories that should not be included in the Git repository. This list can include files generated by the operating system, such as temporary files, as well as files and directories generated by your own code. For example, if you are developing a web application, you may want to include a file in your .gitignore file that contains a list of files and directories that should not be tracked, such as the log files or the uploads directory.
Why Should You Use a .gitignore File?
Using a .gitignore file is important for a few reasons. First, it helps keep your repository organized by ensuring that only the necessary files are tracked. Second, it helps protect sensitive information by keeping confidential files and directories out of the repository. Finally, it helps keep your repository size small, which can be important if you are using a paid hosting service or if you are sharing your repository with others.
How to Create a .gitignore File
The first step to adding a .gitignore file to your repo is to create the file. To do this, open your favorite text editor and create a new file called “.gitignore”. This file can be placed in any directory in your repo, but it is usually placed in the root directory.
Once you have created the file, you can add a list of files and directories that should not be tracked by Git. For example, if you are developing a web application, you may want to add the following lines to your .gitignore file:
- logs/*
- uploads/*
- tmp/*
These lines tell Git to ignore any files or directories that match the pattern. In this case, any files or directories in the logs, uploads, or tmp directories will not be tracked by Git.
How to Add a .gitignore File to a Repo
Once you have created your .gitignore file, you can add it to your repo. To do this, open the terminal and navigate to the directory where your repo is located. Then, type the following command:
git add .gitignore
This command will add the .gitignore file to your repo. You can then commit the change with the following command:
git commit -m "Added .gitignore file"
