Hi Stefano, Thanks for telling me about combine. It is a nice program, but not the same as blm. blm supports any number of one up to many many file arguments and each argument may have a unique operation. combine supports exactly one operation only. Another difference is that combine uses an arbitrary ordering based on the order that lines appear in the input files, whereas blm automatically sorts and uniques each line: that is, the sequence of lines is really converted to a set. As the man page for combine states, their operations are not commutative due to the fact that they try to preserve order. Blm makes no such attempts and is therefore simpler. Best regards,
