Well, I would like filter out the lines which keeps on varying so i can not use -A or -B syntax with grep.
so looking for other better option by which I can grep out those lines. The one clue I can see is since these lines always starts and ends with certain fixed lines, I could use that criteria to extract the lines?
say for example
# Para Starts from below
Please block below URLS.
# para ends
So in the above example if I could filter out the lines between "Please block" and "end" I guess I could achieve the goal but not sure how to extract the same with the help of grep.
Do let me know if you have any other solution.
