This will handle up to 15 signifcant digits:
Code:
 awk ' {total+=$0} END { print total} ' file

This will handle bigger numbers depending on your version of bc:
Code:
#/bin/ksh
total=0
while read value
do
    total=$(echo "$value + $total" | bc )
done < file
echo $total

vm_stat

VM_STAT(1)						    BSD General Commands Manual 						VM_STAT(1)

NAME

     vm_stat -- show Mach virtual memory statistics

SYNOPSIS

     vm_stat [[-c count] interval]

DESCRIPTION

     vm_stat displays Mach virtual memory statistics.  If the optional interval is specified, then vm_stat will display the statistics every
     interval seconds.	In this case, each line of output displays the change in each statistic (an interval count of 1 displays the values per
     second).  However, the first line of output following each banner displays the system-wide totals for each statistic.  If a count is pro-
     vided, the command will terminate after count intervals.  The following values are displayed:

     Pages free
	     the total number of free pages in the system.

     Pages active
	     the total number of pages currently in use and pageable.

     Pages inactive
	     the total number of pages on the inactive list.

     Pages speculative
	     the total number of pages on the speculative list.

     Pages throttled
	     the total number of pages on the throttled list (not wired but not pageable).

     Pages wired down
	     the total number of pages wired down.  That is, pages that cannot be paged out.

     Pages purgeable
	     the total number of purgeable pages.

     Translation faults
	     the number of times the "vm_fault" routine has been called.

     Pages copy-on-write
	     the number of faults that caused a page to be copied (generally caused by copy-on-write faults).

     Pages zero filled
	     the total number of pages that have been zero-filled on demand.

     Pages reactivated
	     the total number of pages that have been moved from the inactive list to the active list (reactivated).

     Pages purged
	     the total number of pages that have been purged.

     File-backed pages
	     the total number of pages that are file-backed (non-swap)

     Anonymous pages
	     the total number of pages that are anonymous

     Uncompressed pages
	     the total number of pages (uncompressed) held within the compressor

     Pages used by VM compressor:
	     the number of pages used to store compressed VM pages.

     Pages decompressed
	     the total number of pages that have been decompressed by the VM compressor.

     Pages compressed
	     the total number of pages that have been compressed by the VM compressor.

     Pageins
	     the total number of requests for pages from a pager (such as the inode pager).

     Pageouts
	     the total number of pages that have been paged out.

     Swapins
	     the total number of compressed pages that have been swapped out to disk.

     Swapouts
	     the total number of compressed pages that have been swapped back in from disk.

     If interval is not specified, then vm_stat displays all accumulated statistics along with the page size.
