I have a file that has list of numbers in these number relate to a website so page for example
I need to loop through the file and for each one go to the webpage and do a grep on it for another key number.
is there a way to do this without download each page ? If I was doing this by command line i would do wget website wait for it to download then do a cat websitename | grep keyword is there way to do it as one command ?
any help or advice would be nice thanks
