Limiting Number of Git Revisions - How
What
Whenever a git commit is made, you are essentially creating a snapshot of the directory tree with some optimisations. This is great for software development workflow. However if you are using git to version control something like a personal knowledge base, keeping snapshots all the way back to origin is unnecessary.
Git provides facilities to prune old commits. We make use of this facility to keep only last 5 commits. This means whenver a new commit is made, the fifth oldest commit is removed. You can verify this with git log.
How
- In your folder under git version control, create/open the file
./.git/hooks/post-commit - Add the following code to it and save the file
git rev-parse HEAD~1 > .git/shallow && git fsck --unreachable && git gc --prune=now
- Make the post-commit hook executable
chmod +x .git/hooks/post-commit
