comment Process Files to create a new file
What values? You haven't shown even a single sample line of your three files, just said that the first file contains commas, and two 24-hour timestamps. Is there anything else in there? What order are the columns? Is file 2 a single integer value, or something else? What should file 3 look like?

comment Why is apt filling up disk space that `apt-get clean` frees?
What makes you think apt is filling your disk with logging? It's filling your disk with packages, and they must have come from somewhere. See help.ubuntu.com/community/AptGet/Howto#Maintenance_commands
