Exact RAM size.

[Rohit khaladkar]

Hi!I have Red Hat linux 4.5 and 5.2 installed on my systems. There is a
application which tells me, how much exact RAM size is required to load
another application.For eg : it would be 20 GB or 2 GB.
Now when I run my script I need to find out the RAM size.But if the server
ordered is of 2GB RAM size , exactly 2GB is never shown by the system. It is
a little less than 2GB.Is there any way I can have a criteria
to tell how much is the exact RAM size.

Thanks!
