Crawl singular URLs:

{"status": 200, "url": "https://domain.com", ...}
...
```

Crawl through a sitemap:

```bash
$ crab crawl:sitemap https://domain.com/sitemap.xml
```

Replace all URLs with a different one:

```bash
$ crab crawl:sitemap https://domain.com/sitemap.xml --prefix-url=https://staging.domain.com
```

Add some cookies/headers:

```bash
$ crab crawl:sitemap https://domain.com/sitemap.xml --cookie auth_token=12345 --header X-Bypass-Cache=1
```

### Filter by Status Code

You can filter the output by it's status code

```bash
# This will only return responses with a 200 OK
$ crab crawl:sitemap https://domain.com/sitemap.xml --filter-status=200
# This will only return responses that are not OK
$ crab crawl:sitemap https://domain.com/sitemap.xml --filter-status=!200
# This will only return responses between 500-599 (range)
$ crab crawl:sitemap https://domain.com/sitemap.xml --filter-status=500-599
# This will only return responses with 200 or 404 (multiple, be aware if one condition is true they all are)
$ crab crawl:sitemap https://domain.com/sitemap.xml --filter-status=200,404
# This will only return responses with a code greater than 500
$ crab crawl:sitemap https://domain.com/sitemap.xml --filter-status=>500
```

### Save Url List in File

You can save the url list to a file

```bash
# This will save the output to a file called output.txt
$ crab crawl:sitemap https://domain.com/sitemap.xml --output-file ./output/output.txt
```

You can save the output to a JSON file
