How to cut text using bash?

Question

bash

the text that contains the string https:\/\/scontent1.kurazh.com\\/6_58_7865_n.jpg , how to extract it and write it to the var variable (for example). Number of lines, file size unknown. The script finds the word https and copies until the word ends with .jpg

, tried to mess with sed, nothing happened. Help me please.

Answer 1

It's not entirely clear what exactly you need?
All URLs ending with .jpg?
It is possible through grep with a regular expression. Just clarify the problem with an example, or try it right away like this:
var=`grep -P -o "https.*\.jpg" text.txt`
