Hey im trying to scrapd emails from this webpage but i keep getting an error, here is the code
wget -q -r -l 5 -O - https://ahrefs.com/blog/find-email-address/ | grep -E -o "\b[a-zA-Z0-9.-]+@[a-zA-Z0-9.-]+\.[a-zA-Z0-9.-]+\b"
my output: -k or -r can be used together with -O only if outputting to a regular file.
