title: Global flags
description: Flags that work on every CLI command.
---
These flags are registered globally by the CLI parser (`packages/cli/src/context/parser.ts`) and accepted on every command.

| Flag                | Description                                                             |
| ------------------- | ----------------------------------------------------------------------- |
| `--help`, `-h`      | Show help for the current command and exit.                             |
| `--version`, `-v`   | Print the installed CLI version and exit.                               |
| `--no-telemetry`    | Disable anonymous telemetry for this run. See [Telemetry](./telemetry). |
| `--telemetry-debug` | Print telemetry events to stderr instead of sending them.               |
| `--logger <level>`  | Set log level (`fatal`, `error`, `warn`, `info`, `debug`).              |
| `--config <path>`   | Load configuration from an explicit file.                               |
| `-y`, `--yes`       | Skip confirmation prompts (use with caution).                           |

`--dry-run` is **not** global; the codemods command accepts it as a per-command flag — see [`codemods`](./commands/codemods).

## Environment variables

| Variable                    | Effect                                                                                                                   |
| --------------------------- | ------------------------------------------------------------------------------------------------------------------------ |
| `C15T_TELEMETRY_DISABLED=1` | Permanently disable telemetry for this user.                                                                             |
| `C15T_DEBUG=1`              | Enable verbose debug logs.                                                                                               |
| `C15T_URL`                  | Override the backend URL the CLI talks to (the value read by `ENV_VARS.BACKEND_URL` in `packages/cli/src/constants.ts`). |
| `C15T_API_KEY`              | API key passed to the backend (read by `ENV_VARS.API_KEY`).                                                              |
| `CONSENT_URL`               | Override the control-plane / dashboard base URL (used for `login`).                                                      |
| `NO_COLOR=1`                | Disable terminal colors.                                                                                                 |
