Thank you David. A typical output file comprises ~200 lines. Most of those files are useless and thus the arrays that contain theirs lines will occupy extra memory. I am running many such scripts concurrently which invoke similar processes several times so I'm wondering if there is a way to erase those arrays from memory upon completion of the execution.
