# Commands (https://optakt.ai/docs/commands)

## On your agent's machine [#on-your-agents-machine]

| `optakt` | Opens the [admin app](/docs/admin-app) |
| `optakt --host <host> --port <port>` | Opens the admin app on another machine |
| `sudo optakt install` | Runs the installer, or continues one that stopped |
| `sudo optakt upgrade` | [Upgrades](/docs/upgrade) to the newest release your licence allows |
| `sudo optakt tune` | Tunes an Optakt-managed database, restarting it if needed. For a server you manage, it sets database-local values and reports server-wide changes for you to apply |

| `optakt version` | Prints the version |
| `optakt help [command]` | Prints help |

On a Mac, run them without `sudo`.

`optakt-secret` is installed beside the service. Your agent's commands use it to fill in a credential; it is not meant to be run by hand.
