> Run abilities, build the site and manage users, tokens and plugins from the terminal.

Run `php cms` from your site folder.

| Command | Does |

| `cms serve --port=8000` | Development server. |
| `cms run` | List abilities. |
| `cms run <ability> key=value …` | Run an ability. Values may be JSON: `cms run entries/create collection=pages title=About 'data={"summary":"Hi"}'`, or pass the whole input with `--json='{…}'`. |
| `cms build` | Build the whole static site. `--strict` fails on warnings, such as a missing image. |
| `cms links:check` | Fail on links, images and anchors in the built site that lead nowhere. External links are left alone. |

| `cms packages:update` | Check the signed update list and [update the core](https://docs.lettern.org/getting-started/upgrading). `--check` only says what's on offer. `--security-only` does what an admin's visit would, for cron. |

| `cms publish:scheduled` | Let scheduled entries go live (run from cron every minute). |

Abilities run from the CLI act with full rights and are logged as `cli` in the audit log. Abilities can opt out of the CLI with `expose: ['cli' => false]`.
