just try: (need: dd, zip, zipinfo, bc, ls, /dev/zero :) dd if=/dev/zero of=data bs=1k count=200 zip data.zip data zipinfo data.zip Archive: data.zip 355 bytes 1 file -rw-r--r-- 2.3 unx 204800 bx defN 27-Aug-04 13:25 data 1 file, 204800 bytes uncompressed, 215 bytes compressed: 99.9% ls -l data* ... 204800 27. Aug 13:25 data ...... 355 27. Aug 13:25 data.zip echo "204800/215; 204800/355" | bc So such archives are possible. _BUT_ I wouldn't try to feed my virus scanner with something like that :) Greetings Daniel -- Join the Navy; sail to far-off exotic lands, meet exciting interesting people, and kill them. ------------------------------------------------------- SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 Save 50% off Retail on Ink & Toner - Free Shipping and Free Gift. http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285 _______________________________________________ Clamav-users mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/clamav-users
