# CLI reference

Use this section to find the right command quickly, then open the command page
for full options and argument details.

## How to use this section

1. Start with {doc}`base` for options shared across the CLI.
2. Pick the command group or command you need from the command map below.
3. Open the linked page for complete autogenerated option reference.

## Command map

| Command | Use it for | Required positional args |
| --- | --- | --- |
| `batdetect2 predict` | Run inference on audio | Depends on subcommand (`directory`, `file_list`, `dataset`) |
| `batdetect2 data` | Inspect and convert dataset configs | Depends on subcommand (`summary`, `convert`) |
| `batdetect2 train` | Train or fine-tune models | `TRAIN_DATASET` |
| `batdetect2 evaluate` | Evaluate a checkpoint on a test dataset | `MODEL_PATH`, `TEST_DATASET` |
| `batdetect2 detect` | Legacy compatibility workflow | `AUDIO_DIR`, `ANN_DIR`, `DETECTION_THRESHOLD` |

## Global options and conventions

- Global CLI options are documented in {doc}`base`.
- Paths with spaces should be wrapped in quotes.
- Input audio is expected to be mono.
- Legacy `detect` uses a required threshold argument, while `predict` uses
  the optional `--detection-threshold` override.

```{warning}
`batdetect2 detect` is a legacy command.
Prefer `batdetect2 predict directory` for new workflows.
```
