Thanks Michael,

The easiest would be to test whether "df -kP" works, and that its output has the same format
as "df -k" does on Linux.

Alternatively - whether FileSystemUtils.freeSpaceKb("/home/michael") works happily. 

Either would be great :)

> The freeSpaceUnix method does not work under HP-UX.  The df command under HP-UX is the
old System V varient and the fields are not in the correct order.   This diff modifies the
code to use the 'bdf' command when HP-UX is detected:
