Today marks the launch of bulkfilepr v0.1.0, a new Go-based command-line tool designed to automate one of the most tedious tasks in repository maintenance: updating standardized files across multiple GitHub repositories. Released on January 16, 2026, this initial release delivers a complete, production-ready tool from day one.

If you maintain dozens or hundreds of repositories with shared configurations—CI workflows, Dockerfiles, CODEOWNERS files, lint configs, or templates—you know the pain of making the same change repo by repo. bulkfilepr eliminates that drudgery by automating the entire workflow: cloning repositories, creating branches, applying file changes, committing, pushing, and opening pull requests via the GitHub CLI.

What’s New

As the first public release, v0.1.0 introduces all core functionality of bulkfilepr:

Three Update Modes - Choose the right strategy for your use case:

  • upsert - Always write the new file (create if missing, update if exists)
  • exists - Only update if the file already exists at the destination path
  • match - Only update if the file exists AND its SHA-256 hash matches an expected value

Safety-First Design - The tool includes comprehensive safeguards to prevent accidental changes:

  • Automatic default branch detection using GitHub API
  • Working tree verification before any modifications
  • Intelligent branch state handling with automatic switching when safe
  • Clean error exits when operations cannot proceed safely

Idempotent Operation - Running the same command multiple times is safe. If the target branch already exists locally or remotely, bulkfilepr exits gracefully without attempting duplicate work—making it ideal for automation scripts and CI/CD pipelines.

Dry Run Mode - Preview what changes would be made before executing them. The --dry-run flag performs all safety checks and evaluates mode conditions without modifying any files or creating branches.

Deterministic Branch Naming - When you don’t specify a branch name, bulkfilepr generates one automatically using a SHA-256 hash of the file content. This ensures reproducibility and makes it easy to identify bulkfilepr-managed branches.

GitHub CLI Integration - Pull requests are created automatically via gh pr create with support for custom titles, bodies, and draft PR creation.

Why It Matters

Repository maintenance at scale is a hidden time sink for many engineering teams. Standardized files should be consistent across your repositories, but keeping them synchronized often means:

  • Manually opening each repository
  • Creating branches one by one
  • Copying or updating files repeatedly
  • Committing and pushing changes
  • Opening pull requests individually

bulkfilepr transforms this multi-hour (or multi-day) process into a single command. Beyond the time savings, it reduces human error, ensures consistency, and provides auditability through deterministic branch naming and idempotent operations.

The safety-first design means you can run bulkfilepr with confidence. The tool refuses to proceed unless you’re on the default branch with a clean working tree, automatically switches branches when safe to do so, and protects your work by refusing to operate on dirty repositories.
