Given that you've got 5GB of free virtual, you could just do: dd if=/dev/zero of=my-big-file bs=5g count=1 However, it's probably better if you restrict your buffer size to something that will fit in real memory. If that happens to be 5MB, then you do it like so: dd if=/dev/zero of=my-big-file bs=5m count=1024 Just make sure that bs and count multiply to the size of the file you want. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Q: How do you make the gods laugh?
