Dear all:

I have a file contain a lot of string.
ex.

ABADSFASVASDF
ASDFASFASVASDF
ASDFASFDASDF
VASDFASVAS
ASVASDFASDFASDF
ASVASDFASDFASDFA
ASDFASVASDFAF
ASDFASFDAF


I have to slice them if they match some criteria.
It not hard for ruby.

The file i had to process is very very hug (>100G).
In order to speed up my program , i use gun_parallel to split the file
and pipe to my script.

Is ts possible to drop parallel and use pure ruby to instead?

Thanks

Felix
