This script is useful when you want to change multiple part of multiple files in multiple git repositories in bulk. Script is creating a new branch from the given base branch and committing changes into it. Maybe push to remote also can be added with small change.

I used this script for changing the auto scaling config inside the Cloudformation templates for multiple micro services in our project.

First clone repository

git clone https://github.com/omerkarabacak/bulk-find-and-replace-in-git-repositories.git

In config.json file, change these;

• Add your new branch names and repositories in repository_list
• Add texts to find and replace find_and_replace_list
• Add files to check in file_list
• Change commit message commit_message
• Change base branch base_branch
• Change repository directory if needed repositories_directory
• Change author name repository_author.name
• Change author email repository_author.email
• Change SSH key path if you need something specific ssh_key

You are ready to go!

There are 2 options. You can build your Docker image with Dockerfile or use ready public Docker image from Docker Hub.

Build Docker image:

docker build -t bulk-find-and-replace-in-git-repositories:1.0 .

Run with built local Docker image:

docker run --rm -v $(pwd)/config.json:/app/config.json -v $(pwd)/repositories:/app/repositories -v ~/.ssh/id_rsa:/root/.ssh/id_rsa bulk-find-and-replace-in-git-repositories:1.0

Run with public Docker image:

docker run --rm -v $(pwd)/config.json:/app/config.json -v $(pwd)/repositories:/app/repositories -v ~/.ssh/id_rsa:/root/.ssh/id_rsa omerkarabacak/bulk-find-and-replace-in-git-repositories:1.0

First create virtual environment

python3 -m venv env

Enter virtual environment

source env/bin/activate

Install dependencies

pip install -r requirements.txt

Run script

python findandreplace.py

Tested with 3.6.8
