I want to redirect the output from a command to a file. fine no problem except when you do this the output is buffered and does not actually get written until the buffer is flushed. I want to be able to read the file with another process while the first is going on. but I am not seeing the output as expected. is there a way force a no buffer when you redirect a processes output to a file?

for exampe:

hdiutil burn ~/Desktop/backup.dmg -noverifyburn -eject -testburn > ~/Desktop/arcresults 2>&1 &

now while that is in the background I want to read from ~/Desktop/arcresults
but the buffered so I see the output late.
