[General] Any linux gurus?

[Stephan Henning]

No, iostat will normally just dump to the terminal window, but I'd like to
pipe it's output to a file so I can parse it later.

My end goal here is to be able to generate a log of iostat output while I
run this program, I'm trying to determine exactly how hard this program is
hitting my harddrive and at what points during it's run does it access the
drive the most frequently.

I've done something similar in bash before, but it is rather clunky.

I'll take a look at exec and see if I can use it.
