 No...just save the following out as a script, and run it:

#!/bin/sh
physical=`grep Mem: /proc/meminfo  | awk '{print $2}'`
used=`grep Mem: /proc/meminfo  | awk '{print $3}'`
buffers=`grep Mem: /proc/meminfo  | awk '{print $6}'`
cache=`grep Mem: /proc/meminfo  | awk '{print $7}'`
swapused=`grep Swap: /proc/meminfo  | awk '{print $3}'`
echo $(( $physical - $used + $cache + $buffers - $swapused )) 


 The 'echo' should be the last line of the script, as it needs all the
variables to have been setup.
