NAME
       filemem - show a list of a file's pages cached in memory

SYNOPSIS
       filemem filename

DESCRIPTION
       Filemem	is  a  utility	that  can  determine which pages of a file are
       cached in memory.  In Mach, pages of a file are	cached	on  demand  by
       page   faults.	 Pages	 remain	 in  memory  even  after  they	become
       unreferenced, and are released when memory becomes scarce.

       Filemem provides a way to determine which parts of  a  file  are	 being
       used.   For  example, filemem can be used to help scatterload a file by
       showing which parts of an  executable  image  are  in  memory  after  a
       certain	operation.   After  determining	 which	pages  are resident in
       memory, the program pagestuff(1)	 can  be  used	to  show  the  symbols
       residing on that particular page of a file.

       The  output of filemem is a list of logical page numbers, starting from
       page zero at the beginning of the file.	The page size is the  same  as
       the machine-independent page size of the system.

FILES
       /dev/kmem
