Hi Dev,

You can look in /proc/meminfo
http://unixfoo.blogspot.com/2008/02/know-about-procmeminfo.html
The memory is shared between userspace and kernel space and the amount
of memory available changes dynamically as the system is running.
Be aware that Cached memory is quite dynamic, and the system will
throw away cache pages to make space if it needs to.
