Repository cleanup with git gc
git gc (garbage collection) helps use repository storage more efficiently by organizing Git objects. It can combine loose objects into pack files and clean up unnecessary data.
git gcGit can also perform some maintenance tasks automatically. You can run git gc manually when repository maintenance is needed.
Packing and maintenance options
Git objects can initially be stored as separate files. Packing these files over time can improve storage and access efficiency.
git gc --auto
git gc --aggressive--auto allows Git to perform maintenance when needed. --aggressive performs a more intensive packing operation and may take longer.
Practice Run the git gc maintenance command
Run garbage collection in the repository using the automatic maintenance option. Then print a message indicating that the operation is complete.
Starter code
