question about files?
I was at a vendor demonstration last week, and the presenter had his laptop on screen where we could see the product demo. He had a Unix terminal screen up and created an empty file, but he used some command (I wish I had caught how he did this) to actually make the empty file a certain size. Does anyone know how this is accomplished? In this instance, he used it to show how a 20 Mb file would be transferred through a router.


Anyone know how this was possibly done?
