Introduction

This is a Python program that calls muffet on a whole website and then filters and displays the HTTP errors.

Note: It can take a couple of minutes to run if the website has a lot of URLs.

How the Program Exits

Exits with error code 1 if at least one error is found, as specified with --errors flag. Otherwise exits with code 0. Note that errors set as --warnings will always exit with code 0.

Program Arguments

url
- The URL to scan. Please include https:// or http://. (e.g. https://google.com)
-h, --help
- show this help message and exit
-e ERRORS [ERRORS ...], --errors ERRORS [ERRORS ...]
- Specify one, many or all error codes to be filtered (e.g. -e 404, -e 403 404, -e all). Use -e all to show all errors.
-w WARNINGS [WARNINGS ...], --warnings WARNINGS [WARNINGS ...]
- Specify one, many or all error codes to be filtered as warnings (e.g. -w 404, -w 403 404, -w all). Use -w all to show all warnings.
