Presets

Presets are predefined options (URL path, match regex, and extract regex) that can be used to organize and simplify different use cases. The preset definitions are stored in ~/.chronos as JSON files

$ cat ~/.chronos/robots.json
{
        "path": "/robots.txt",
        "match": "Disallow",
        "extract": "(?:\\s)(/.*)"
}
$ chronos -pr robots -t example.com
$ # equivalent to...
$ chronos -p /robots.txt -m Disallow -e "(?:\\s)(/.*)"

Example usage

Extract paths from robots.txt files and build a wordlist

$ chronos -t example.com -p /robots.txt -m Disallow -e "(?:\\s)(/.*)" -o robots_wordlist.txt

Save all versions of a web page locally and filter out a specifc status code

$ chronos -t http://example.com/this_is_403_now_but_has_it_always_been_like_this_question_mark -fs 403 -od output
