Suppose there is a text file test.txt. It contains text and links to resources such as https://example.com/kqodbjcuic49w95rofwjue. How can I extract only the list of these links from there? (preferably via bash, but not required)
I tried this solution:
sed 's/^.*href="\([^"]*\).*$/\1/'
But it didn't help me.
grep -o "/((?:(?:http|ftp|ws)s?|sftp):\/\/?)?([^:\/\s.#?]+\.[^:\/\s#?]+|localhost)(:\d+)?((?:\/\w+)*\/)?([\w\-.]+[^#?\s]+)?([^#]+)?(#[\w-]*)?/gm" test.txt
will display all URLs inside the file.
(The regex comes from BSimjoo's link)
