[SunHELP] How can I find the open files in a specific path?

Hi there;
 
I want to do some sort of processes on the home directory of some users on
several Solaris servers but I don't want to touch it if 'any' file is open
in there.
'fuser' command doesn't help me and I don't have 'lsof' installed on the
servers. Do you know any other way that I don't need to install anything
extra on about 50 servers with different flavours of Solaris 2.6,7 and 8?
 
Thanx;
-- Sbnm
