Unbufferred output in bash shell

Hi, when I redirect the output of a program to a file, e.g. myprog > file.txt, the shell seems to buffer the output before writing to the file. From my observation on my machine, the buffer seems to be 4K. Is there a way to let bash immediately write any output strings to file (not using buffer at all)?
