I have a list of n number (n is known) of URLs. How can I remove the protocol name from the URL?

Eg : from https://xyz.com, I want to fetch xyz.com part only.

Using GNU grep and PCRE matching,

grep -oP 'https://\K\S+' file

That outputs the non-spaces following "https://"

  • Thank you it worked :) – DedSec Aug 26 '20 at 17:55
  • Yes this will also work :) – DedSec Aug 26 '20 at 18:04
  • If you want to do that, use '(http|https)://...' -- [http,https]://... means "an h or a t or a p or an s or a comma followed by colon slash slash. More succinctly, use https?://... which means "http followed optionally by an s followed by colon slash slash" – glenn jackman Aug 26 '20 at 18:12
  • Sorry about that! The (http|https)://... actually works better where I tested the [ ] and it returned all with h, t or p in them regardless of where they were in the beginning of the line. It was giving me a false positive because that was all I had in my file. I stand corrected. =) – Terrance Aug 27 '20 at 14:02

How about using awk with F option and text redirection?

awk -F'^http[s]?://' '{print $2}' fileName > outputFile

Or sed with i option

sed -i s/'http[s]\?:\/\/'// fileName

Here is a simple awk invocation:

$ awk -F// '{print $NF}' fileName

-F specifies the field separator. $NF prints the last field.

You might need to use double quotes around //.
