Real brief intro to how hashes would be useful here...
Each line in the input file gets converted to a unique fixed-length hash. This hash
is sorted in a table and the sorting method is very efficient.
To check if a new entry already exists is a simple matter of:
1) hash the new line
2) lookup the new hash in the hash table for the old file
Because there's no regex searches or other manipulation it's quick and efficient.
