Hi ravi45722

..I am dealing with bigger files. If I use open its occupying my primary memory..

How is that so? Have you profiled your code?
More so, I didn't see how you are using open in your code as shown in your post.

If I didn't misunderstood your requirement, there are several alternative to dealing (data munging) with large files. File::Slurper, Path::Tiny and others

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.
