"lsof" isn't native to Solaris, not even at its (current) "Solaris 10"
release.

Judging by the BSD man pages, its native availability there seems patchy.


So could I suggest, if reasonably possible, code of the form:

   if [ -x @LSOF@ ]
   then
      ... @LSOF ...
   else
      ... @FUSER@ ...
   fi

recognising that some sort of additional error-handling for the @FUSER@
case might be necessary?

Need the absence of "lsof" be a show-stopper, so long as "fuser" is
present?



Incidentally I recommend the man-page site:
    http://www.freebsd.org/cgi/man.cgi?

It allows you to see man pages for various versions of various OSes, not
just BSD, but Solaris, Linux flavours, HPUX, ...  Well worth bookmarking.
