Install and run

otlite install ivre
Installs ivre==0.9.20 into its own virtualenv. otlite lists what it will install and asks before it starts.
otlite run ivre -- --help
Ivre has no typed inputs. Everything after -- goes to ivre unchanged, so pass its own arguments there.

Linux and macOS, no Docker. It uses your Python and pipx when both are there, and otherwise brings its own Python. About otlite · otlite docs

What it takes

Ivre has no typed inputs, though it works on domain, IP address. Pass its own arguments after --; otlite run ivre -- --help lists them.

What a run leaves

Every run is saved under results/ where you run otlite (or --output, or OTLITE_RESULTS_DIR): what the tool printed, a sidecar with how it ran, and an envelope.

results/ivre/johndoe/<time>_ivre_johndoe_<run id>.txt
results/ivre/johndoe/<time>_ivre_johndoe_<run id>.meta.json
results/ivre/johndoe/<time>_ivre_johndoe_<run id>.envelope.json

{
  "envelope": 1,
  "tool": "ivre@0.9.20",
  "runtime": "otlite",
  "input": { "target": "johndoe" },
  "case": null,
  "started_at": "…", "ended_at": "…", "duration_ms": …,
  "exit_code": 0,
  "status": "complete",
  "entities": [{ "type": "url", "value": "…" }, …],
  "warnings": [],
  "output": { "path": "results/ivre/johndoe/<time>_ivre_johndoe_<run id>.txt", "sha256": "…", "bytes": … }
}

The envelope's shape, the same for every tool; values elided. Its entities are the emails, domains, IP addresses and URLs found in the output, or the tool's own when it prints them.

otlite results --tool ivre

otlite extract ivre

otlite diff ivre johndoe

List the saved runs, pull out every indicator, or compare the two latest runs against the same target.

With other tools

Batch runs can't pass it a value, so run it on its own.
