I have a PC with Intel(R) Pentium(R) CPU G640 @ 2.80 GHz and 8 GB of RAM. I am running Scientific Linux 6.5 on it with EXT3 filesystem. On this setup, what is the fastest way I can do a sort -u on a 200 gigabyte file? Should I split the file into smaller files (smaller than 8 GB), sort -u them, put them together, then split them again in a different size, sort -u again, etc.? Or are there any sort
