Reading file after a particular line in file

Ruby
1

Hello All,

  I would like to read a file in ruby. It is a 2G file, but

contain useless data in the beginning portion of the file.

There is a particular pattern towards the middle of the file after
which useful data begins. Is there a way to grep for this pattern and
then read every line henceforth, but ignore all lines previous to line
on which pattern found?

Thanks,
Vandana

If you don’t know where it is, then you’ll probably have to parse each
line until you reach it, then continue on.

Grep is going to have to read the file to find that pattern anyway.
