This repository is a collection of shell scripts for installing, upgrading, and managing MagicMirror², an open-source smart mirror platform. The scripts automate the setup of Node.js, npm, pm2, and the MagicMirror application on Raspberry Pi and other Linux systems, as well as macOS. They handle tasks such as initial installation, version upgrades, pm2 process management, screensaver disabling, disk cleanup, and switching to browser-over-server mode. The scripts are designed to be executed via curl pipe to bash, ensuring users always run the latest version. While primarily operational, the cleanup.sh script stands out as a well-structured, reusable utility for reclaiming disk space on any system.
