I've got two similar large files with one word per line and they're sorted. Each file has a few words not in the other. I typically identify the unique words in the file using diff,grep,cut. When the files are too big (2Gig) diff dies with "memory exhausted".
I want to search for the unique words in file1 but I might need to ping-pong since neither file is a superset of the other. I don't want to be limited by physical RAM as the file sizes exceed RAM. I assume I'm not the first to have this problem. Can someone point me to perl code?
