in thread Filtering lines from one file from another
mertserger,
The problem with comm is that it requires the files to be sorted (which they are not). If antonn doesn't need to preserve order than this is a fine solution. It is actually a fairly difficult problem to solve if you self-impose a number of constraints such as order preservation and arbitrarily large files.
