I was retrieving this iso:
ftp://ftp.slackware.no/pub/linux/ISO-images/Slackware/Current-ISO-build/slackware-10.0-DVD.iso
I killed wget and then I resumed it with wget -c (file was downlaoded for 2285260288 bytes)
here's the output:
--19:31:47-- ftp://ftp.slackware.no/pub/linux/ISO-images/Slackware/Current-ISO-build/slackware-10.0-DVD.iso
