LinuxGSM is a command-line tool written in Bash for deploying, managing, monitoring, and updating dedicated game servers on Linux. It supports over 150 games, primarily through SteamCMD integration, and provides a modular architecture with commands for install, start, stop, update, validate, backup, console access, and alerting. The system uses tmux for session management, configurable per-game default configurations, and a plugin-style alert system supporting Discord, Email, Slack, Telegram, and more. The codebase is heavily modular with consistent logging and error handling, but suffers from significant duplication in per-game config files and a monolithic game info parsing module. It is actively maintained with extensive CI/CD workflows for validation and issue triage.
