Hi Folks. Do you guys happen to have any suggestions for comparing 2 files line by line that don't involve loading all the lines into memory? I'm trying to compare two files that are each over 300MB in size. My system doesn't have enough memory to handle loading all the file lines into a hash. I've tried the readline approach but it takes forever to run. Unfortunately, I'm not able to load the data into a database either - even a Berkeley DB. Any ideas would be appreciated.
