How do I remove git commits history up to the last 27th and only keep these last 27 commits?
To remove git commits history up to the last 27th and only keep these last 27 commits, follow these steps:
- Find the commit hash of the 27th commit from the end: Run the command
git log --oneline | tail -27 | head -1. - Reset the HEAD to the 27th commit: Run the command
git reset --hard <commit-hash>, replacing<commit-hash>with the commit hash obtained in step 1. - Force push the changes to the remote repository: Run the command
git push -f.
This process will effectively remove all commits before the last 27 and only keep the last 27 commits in the git history.
