How to filter only the last 'n' lines of a grep output?
I am running a grep query for searching a pattern, and the output is quite huge. I want only the last 200 lines to be displayed, and I am not sure if tail will do the trick (can tail read from std in/out instead of files?).
Please help me out.

Code:
grep <pattern> <file> | tail -200
