thanks jim,

i jabe heard this before, of a file not being able to be bigger than 2G. Is this because this is the default? If my ulimit for file is set to say 10G, then can I create a file bigger than 2G? Or are there some other programs that also have limits set to 2G, so even if I created it for 5G on my unix box, it might still give me some problems?

thanks
