Well basicallly, I was wondering the best way of creating a large dummy file, from 1 gig and larger. The only way i can think of doing it is through a loop which echos a series of characters to a file. I want to be able to see speed with hard drives and web servers, Like dl and upload rate. If you have any other ways than waiting for a text document to get large, which takes forever, let me know. Thanks, Swatward

I'd check the parameters, but something like:

dd -if=/dev/random -of=testfile -bs=1GB


should work nicely on unixlikes.

If you're using Windows, you can create the file then use SetEndOfFile() to make a 1GB file. If you want to actually write stuff to that file, it's a different matter though.
