How to extract domain name from url?

Question

How do I extract the domain name from a url using bash? like: http://example.com/ to example.com must work for any tld, not just .com

Answer 1

One solution that would cover for more cases would be based on sed regexps:

echo http://example.com/index.php | sed -e 's#^https://\|^http://##' -e 's#:.*##' -e 's#/.*##'

That would work for URLs like: http://example.com/index.php, http://example.com:4040/index.php, https://example.com/index.php
