I have a very long text file (> 9M lines)
and I need to extract certain information from it, but I am failing :(

I am trying to write a script that searches through the textfile for a KEYWORD or KEYPHRASE, and copies the (whole) line and the 7 lines directly beneath.
It should do this for every time the keyword/keyphrase appears in the text file.

Please help
