Searching Freshmeat <http://freshmeat.net/> in the "Software" section turns up a bunch of promising shell utilities, most (all?) of which should work on Irix. Apparently, examples include `overwrite`, `wipe`, `srm` and "secure delete." I've also seen a `saferm` mentioned somewhere, but didn't see it on Freshmeat. Personally, I still do something like: dd if=/dev/urandom of=file_to_erase bs=123k count=1 (but I've rarely been accused of keeping up with the times :-) If you do it manually, the key thing is to not leave temporary or otherwise orphaned copies on disk, as most editors will do. --- Send mail for the `bblisa' mailing list to `[EMAIL PROTECTED]'.
