Netlify Redirect Updater

A command-line utility to update destination URLs in Netlify _redirects files using CSV mapping files. Supports both single-site updates and bulk project folder processing via an interactive shell script.

---

✅ Features

• Updates only exact matches to avoid unintentional changes
• Preserves formatting and untouched lines
• Visual HTML diff report for QA
• Supports per-project folder structure for bulk processing
• Virtual environment setup and dependency installation handled automatically
• Interactive CLI with built-in pre-checks

---

🏁 Quick Start (Recommended)

./run_script.sh

This launches an interactive prompt to choose between:

1. Single-site update
2. Bulk project update

The script:

• Checks for required files
• Creates a virtual environment (if needed)
• Installs pandas
• Runs the appropriate updater

📁 Folder Structure

Single-site:

/your-folder/
  redirects.csv
  _redirects

Bulk (multi-project):

/projects/
  /site-a/
    redirects.csv
    _redirects
  /site-b/
    redirects.csv
    _redirects

🧪 CSV Format

Your redirects.csv must have a header:

old_url,new_url
https://your-site.com/old-path,https://your-site.com/new-path

⚙️ Dependencies

• Python 3.7+
