How to Clear Git Cache

Clear Git Cache

Git, a cornerstone in the world of software development, is a distributed version control system that allows developers to track and manage changes to their codebase. One of its integral features is the Git cache, a mechanism that stores information about the repository to expedite Git operations. However, there are instances when it becomes necessary to clear this cache, such as when changes are not being recognized or when the cache becomes cluttered with unnecessary files. This comprehensive guide, designed for intermediate users with a basic understanding of Git and its command-line interface, will walk you through the process of clearing the Git cache.

Understanding Git Cache

The Git cache, also known as the staging area or index, is a temporary storage area where Git keeps track of the changes that are to be committed to the repository. It’s essentially a snapshot of your project that Git uses to speed up operations and reduce the time it takes to switch between different versions of your code.

The cache plays a crucial role in Git’s performance, but there are situations when you might need to clear it. For instance, if you’ve updated your .gitignore file to ignore certain files, but those files were already tracked by Git, you’ll need to clear your Git cache to apply these changes.

Clearing Git Cache

Clearing Entire Git Cache

Clearing the entire Git cache is a straightforward process that involves a few simple commands. The first command you’ll need is git rm. This command, when used with the -r (recursive) and --cached options, removes all files from the index, effectively clearing the cache. Here’s how you use it:

git rm -r --cached .

After running this command, all files are removed from the Git cache. However, you’ll likely want to add back the regular files (the ones you did not want to ignore) to the index. To do this, use the git add . command. This command stages all changes in the current directory and its subdirectories for the next commit. Here’s how you use it:

git add .

Finally, you’ll want to commit these changes. To do this, use the git commit -am 'Removed files from the index (now ignored)' command. This command creates a new commit with a message indicating that files have been removed from the index. Here’s how you use it:

git commit -am 'Removed files from the index (now ignored)'

Clearing Specific Files from Git Cache

There may be instances where you only want to remove a specific file from the Git cache. In such cases, you can use the git rm --cached filename command. Replace filename with the name of the file you want to remove from the cache. After running this command, the specified file is removed from the Git cache. Here’s how you use it:

git rm --cached filename

After removing the file from the cache, you’ll want to commit this change. To do this, use the git commit -am 'Removed specific file from the index (now ignored)' command. This command creates a new commit with a message indicating that a specific file has been removed from the index. Here’s how you use it:

git commit -am 'Removed specific file from the index (now ignored)'

Caching in GitHub Actions

Caching is a critical aspect not only in Git but also in GitHub Actions. Caching dependencies and other frequently reused files enable developers to speed up their GitHub Actions workflows and make them more efficient. GitHub Actions provides cache actions that simplify caching implementation. It’s essential to strike a balance between cache size and freshness. Identifying the right artifacts to cache is crucial to achieving maximum performance gains.

Troubleshooting Common Issues

Sometimes, even after updating your .gitignore file, you might notice that Git is still tracking files that should be ignored. This usually happens because Git’s cache hasn’t been refreshed to reflect the changes in .gitignore. To fix this, you can use the git rm -r --cached . followed by git add . commands to refresh the cache. Also, remember that .gitignore patterns are case sensitive, so ensure your .gitignore patterns match the case of your files exactly.


Clearing your Git cache is a crucial skill when working with Git, especially when you’ve made changes to your .gitignore files. By understanding how to clear the entire Git cache or specific files from the cache, you can ensure that Git is accurately tracking the files in your repository. As you continue to work with Git, remember that understanding the root causes of issues is just as important as knowing the solutions. Keep exploring, keep learning, and happy coding!
