How to use wget to download HTTP error pages?

Question

wget normally stops when it gets a HTTP error, e.g. 404 or so. Is there an option to make wget to download the page content regardless of the HTTP code?

Answer 1

Use curl when wget fails.

#!/bin/bash

if ! wget $1 
    then curl -R -O $1
fi

Usage (saved as wget.sh):

404 error will be saved with curl:

$ ./wget.sh http://www.google.com/asdasdasdasd.html

Working URL will be saved with wget:

$ ./wget.sh http://www.google.com/
