Remember: Just because you're paranoid doesn't mean "they" are NOT out to get you... ---------------------------- First the legal mumbo-jumbo. ---------------------------- Wipefile v1.2 and Wipefree v1.2 are Copyright (C) 1994 Trever Miller These programs are free software; you can redistribute them and/or modify them under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.

You must specify one writable directory per filesystem for the temporary file to be created in. Assuming you have 2 partitions, "/" and "/partition2", and writable directories called "tmp" : wipefree /tmp /partition2/tmp This would effectively overwrite all unused portions of those partitions. Handy if you've been editing a secret document and your editor likes to create temporary files all over the place & you fear your enemies might come along and "spatch disk /" or it's equivalent. I'd recommend running this once a via cron when the filesystem is going to be otherwise idle. Maybe once a week (or day if you're excessively paranoid) ----------------------------------------------------------------------------- You can contact me via the following three methods (in order of preference) internet : bug@cyberdex.cuug.ab.ca millertr@cuug.ab.ca ambush_bug@wooga.cuc.ab.ca quics : tamiller snail-mail : Trever Miller Suite #557 918 - 16Ave N.W.
