This script automates the process of updating specific dependencies within package.json files of child sites contained in multiple monorepos. It is designed to selectively update sites based on the current version of a set of dependencies, streamlining the maintenance and upgrade process of projects within a monorepo structure.

• Selective Dependency Updates: Targets updates based on the current ("from") version to a new ("to") version.
• Caret Version Handling: Accurately processes version strings with carets (^), ensuring compatibility with semantic versioning.
• Automated Git Workflow: Integrates with Git to automate branching, stashing, committing, and pushing changes.
• Enhanced Console Output: Provides colorful and emoji-enhanced output for better readability and user experience.
• Update Summary: Outputs a summary of all updated sites at the end of the script's execution, indicating the old and new versions.

• jq: A lightweight and flexible command-line JSON processor, required for parsing and updating package.json files.
• Git: Must be installed and configured for your user account.
• Bash Shell Environment: The script is written for Bash, which is available by default on macOS.

If you do not have jq installed, you can easily install it using Homebrew:

brew install jq

Open a terminal and navigate to the directory where you've saved updateSites.sh. Then, run the following command to make it executable:

chmod +x updateSites.sh

This command changes the script's permissions to allow it to be run as a program.

With the script now executable, you can run it directly from the terminal by specifying the --from and --to version parameters as arguments. Here's the syntax based on your request:

./updateSites.sh --from 12.4.1 --to 12.7.0

Or, if you've placed the script in a directory that's included in your PATH, you can run it without the ./ prefix from any location:

updateSites.sh --from 12.4.1 --to 12.7.0

This command tells the script to look for sites within each monorepo that are currently on version 12.4.1 and update them to version 12.7.0.
