# dbatools

> A free and open source PowerShell module with 727 commands for SQL Server administration — migration, backup and restore, availability groups, agent jobs, security, and instance configuration. Runs on Windows, and on Linux and macOS for the commands that do not depend on Windows-only APIs.

Every command below has a reference page with its synopsis, full description, syntax, worked examples and a parameter table. Append `index.md` to any command URL for a plain markdown copy — for example `https://dbatools.io/Restore-DbaDatabase/index.md`.

Availability is derived from the module source rather than the published index, because the `Availability` field in dbatools-index.json reports every command as cross-platform. Commands marked Windows-only depend on the registry, WMI, SMO on .NET Framework, or other Windows-only APIs.
