git gc
Clean up unnecessary files and optimize the local repository
This command is used to cleanup unnecessary files and optimize your local repository.
It does this by compressing log files, removing old and unnecessary objects, and generally ensuring that your repository is running as efficiently as possible.
By default, git gc runs in the background and performs many different cleanup tasks. However, the command can be modified with certain flags to perform specific types of cleanup. For example, git gc --aggressive forces the command to optimize the repository even further. The --auto flag allows the system to decide if it needs cleanup. And git gc --prune=now can be used to remove objects that are no longer pointed to by any branch or tag immediately.
