bash scripting

[Eugene Sevinian <sevinian@aya.yerphi.am>]

Hi, ppl, 
I would like to know, is it possible to fork the standard stdout
of some command into another two or three pipelines. The idea is to avoid
unnecessary disk load during temporary file writing/reading. So I need
something like this:

command1 | command2 | command3 | command4 > file1 
                     \->command5 | command6 > file2
                      \->command7 | command8 > file3       

Does bash allow such things?
TIA,
	Eugene Sevinian
