If storage is a problem, try

This only needs to keep 1 copy of each in storage while the sort need
all records in storage..

If the records are large, the KEYONLY option is useful to have it keep
only the first 20 byte of each record in the lookup table. And to
straighten the pipe the NOT stage comes handy in this case:

< file  | not lookup 1.20 autoadd keyonly | > newfile
