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 | User Scanner receives |
| --- | --- | --- |
| Username | `otlite run user-scanner -- u:johndoe` | `user-scanner --username johndoe` |
| Email | `otlite run user-scanner -- e:ada@example.com` | `user-scanner --email ada@example.com` |

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

## Before you run it

- **Dual-use.** otlite prints this before installing it: You are solely responsible for how you use these tools and for complying with all applicable laws. Use them only on targets you are authorized to investigate.

## What a run leaves

- `results/user-scanner/johndoe/<time>_user-scanner_johndoe_<run id>.txt`
- `results/user-scanner/johndoe/<time>_user-scanner_johndoe_<run id>.meta.json`
- `results/user-scanner/johndoe/<time>_user-scanner_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 user-scanner` lists saved runs, `otlite extract user-scanner` pulls out indicators and `otlite diff user-scanner 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.
