How to clear git commit history

I'll help you clear Git commit history. Here are several methods, from least to most destructive:

Method 1: Soft Reset (Keep Working Directory)

If you want to keep all changes but reset to initial state:

# Reset to first commit, keep all files staged
git checkout --orphan new-branch
git add -A
git commit -m "Initial commit"
git branch -D main
git branch -m main
git push -f origin main

Method 2: Hard Reset (Common Approach)

Start fresh but keep current files:

# Create orphan branch with current files
git checkout --orphan temp-branch
git add -A
git commit -m "Fresh start"
git branch -D main
git branch -m main

# Force push to remote
git push -f origin main

Method 3: Completely Fresh Repository

If you want to completely erase history and start new:

# Remove .git directory
rm -rf .git

# Reinitialize git
git init
git add .
git commit -m "Initial commit"

# Set remote and force push
git remote add origin <repository-url>
git push -f origin main

Method 4: Interactive Rebase (Selective History)

If you want to squash many commits into one:

# Squash all commits into one
git reset $(git commit-tree HEAD^{tree} -m "Initial commit")

# Alternative: rebase interactively
git rebase -i --root
# Then mark all commits except first as 'squash'

Important Notes:

⚠️ Warnings:

1. Force push (-f) will overwrite remote history
2. Collaborators will need to reclone or reset their local repos
3. Lost commits cannot be easily recovered

Before Proceeding:

# Backup your current state
git branch backup-branch

# Verify remote
git remote -v
git log --oneline -5

After Clearing History:

# Tell collaborators to:
git fetch origin
git reset --hard origin/main
# Or they should reclone entirely

Recommended Workflow:

# 1. Backup current branch
git branch backup-main

# 2. Create new orphan branch
git checkout --orphan clean-main

# 3. Add and commit files
git add -A
git commit -m "Initial commit"

# 4. Delete old main and rename
git branch -D main
git branch -m main

# 5. Force push
git push -f origin main

# 6. Clean up local backup
git branch -D backup-main

Alternative: Shallow Clone (If You Can't Force Push)

If you don't have permission to force push:

# Clone with only last commit
git clone --depth 1 <repository-url>

# Continue working from there
