I have a file which consists of a URL. I'm trying to get the URL from that file using a shell script.

In the file, the URL is like this:

('URL', 'http://url.com');

I tried to use the following:

cat file.php | grep 'URL' | awk '{ print $2 }'

It gives the output as:

'http://url.com');

But I need to get only url.com in a variable inside the shell script. How can I accomplish this?
