Combine Git repository maintenance
You can combine maintenance, cleanup, and verification tasks to keep a Git repository healthy. git gc organizes objects, git prune removes unreachable objects, and git fsck checks integrity.
git gc
git prune --dry-run
git fsck --fullPreviewing and verifying before cleanup helps reduce the risk of accidental data loss.
Practice Create a maintenance and verification sequence
First run Git garbage collection. Then preview the removal of unreachable objects and finally perform a full integrity check. Print a completion message at the end.
