There is a txt file with a list of url of the form(100k lines) without http://and https://
I need to save in a separate file only those urls in the source code of which pages contain certain text
For example,"Statistic and a Parameter"
I tried to implement this task using a .sh script, because I need to run the script on Ubuntu, but I could not figure it out with curl.
Thank you in advance for your help!
