otlite is the no-Docker edition of OTInstaller for Linux and macOS: [install it](https://otinstaller.com/otlite) with `curl -fsSL https://get.otinstaller.com/otlite | sh`.

## Run it

| Input | otlite command | Blackbird receives |
| --- | --- | --- |
| Username | `otlite run blackbird -- u:johndoe` | `python blackbird.py --username johndoe` |
| Email | `otlite run blackbird -- e:ada@example.com` | `python blackbird.py --email ada@example.com` |

Arguments after `--` that aren't typed inputs go to the tool unchanged.

## Before you run it

- **Runs from its source folder.** It reads data files by relative path, so otlite starts it inside its own checkout.

## What a run leaves

- `results/blackbird/johndoe/<time>_blackbird_johndoe_<run id>.txt`
- `results/blackbird/johndoe/<time>_blackbird_johndoe_<run id>.meta.json`
- `results/blackbird/johndoe/<time>_blackbird_johndoe_<run id>.envelope.json`

The envelope is the same shape for every tool: the tool and version, the input, timing, exit code and status, the emails, domains, IP addresses and URLs found in the output, and the output file's path, hash and size. `otlite results --tool blackbird` lists saved runs, `otlite extract blackbird` pulls out indicators and `otlite diff blackbird johndoe` compares the two latest runs.

## With other tools

`otlite run --all u:johndoe` and `otlite auto johndoe` run it with every other installed tool that takes the same input.
