If you’re a developer working with version control, you know that it’s essential to maintain the integrity of your code by making sure that nothing gets committed to the repo that could cause problems. To do this, you need to add a .gitignore file to your repository. This file contains the patterns of files and directories that should be ignored by the version control system. In this article, we’ll go over how to add a .gitignore file to a repo.
What is a .gitignore File?
A .gitignore file is a special file that tells the version control system which files and directories to ignore. It is essentially a list of patterns that the version control system should not track. This is useful for keeping sensitive files, such as API keys, out of your repository. It can also be used to avoid committing files that are not necessary for the project, such as generated files or log files.
Creating a .gitignore File
The first step in adding a .gitignore file to your repo is to create the file. It is important to note that the file must be named “.gitignore” (note the dot at the beginning) for it to be recognized by the version control system. You can create this file in any text editor, such as Notepad or TextEdit.
Adding Patterns to the File
Once you have created the .gitignore file, you need to add the patterns of files and directories that should be ignored. This can be done by manually entering the patterns in the file or by using a generator. If you are using a generator, you can select the type of files you want to ignore, such as files with certain extensions or files in certain directories. Once you have added the patterns, you can save the file.
Adding the File to the Repo
Now that you have created the .gitignore file, you need to add it to the repo. This can be done by adding the file to the staging area. You can do this by running the git add command with the path to the file. For example:
git add .gitignore
Once the file has been added to the staging area, you can commit it to the repo by running the git commit command.
Verifying That the File is Working
The last step is to verify that the .gitignore file is working as expected. To do this, you can run the git status command. This will show you which files and directories have been ignored. If the file is working correctly, the output should show that the patterns in the .gitignore file have been ignored.
