From experience, no. I think the man page is wrong here, but i haven't looked into the code. My experience says that dump always ``thinks'' in terms of blocks with one kilobyte per block. The `b' is the tape blocking factor only (number of kilobytes per write()), but is not used otherwise in size calculations. Somebody should review the code, and correct the man page. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
