MS-DOS 2.0 added subdirectories, I/O redirection, pipes, filters and a 
few other features copied from Unix. Of course they were mere shadows of 
the actual Unix features and lacked most of the standard capabilities, 
but it was a step in the right direction. It is one of the few steps in 
that direction Microsoft ever took.
