Hello - I hope this is the right place to ask this question; if not, please direct me to the appropriate place. I wish to use the fileutils in a classified environment to transfer data between computers and removable media. In order to do this is is important that cp (and any related utilities) copy only the specified files without padding partial blocks with other data from the source filesystem (padding with a constant such as zero would be fine). As an example, if a number of classified files (filesc) and an unclassified file (fileu) reside on the same disk, a cp of fileu to a floppy disk should never include any parts of filesc. Are cp and friends safe in this regard? Thanks! keith Keith Outwater Principal Engineer Raytheon Missile Systems Tucson, AZ (520) 794-2518 [EMAIL PROTECTED] nzbɚXX~)^إ !f ?+-w~)^إ
