Also spelt "zcat foo.zip > /dev/sd_" for those who don't want to leave a file around they have to delete later. > dd is *not* a better tool for this task - that's just false rumors. I don't know about "better", but it's the right tool for that job, affording you - unbuffered output (oflag=direct) for when you don't want to wait for ages after dd has finished while your system is flushing buffers (or worse, pull the stick/card out while buffers are not flushed because you think copy is ready, leading to funny results) - progress display (either by sending it an USR1 signal or by stating "status=progress". There's a reason a carpenter's shop has more than one tool, but hey, if you insist, you can take out a screw with scissors. Cheers -- t
