Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

a command to free up ram does not exist in linux. You need to check which processes are using the most ram and configure/setup that process accordingly. Linux pretty much caches everything into ram anywayz for performance reasons so the real concern is swap (virtual memory). Check to see if you have enough swap with top, vmstat, etc...
If you don't, either buy more ram or create more swap.
Okay, thanks. I thought so. The RAM usage doesn't vary; it just keeps using more regardless of what I'm doing on the machine, and the usage won't drop. I was just wondering if there was some way to free up processes without closing individual things.

the Linux kernel uses the RAM in a way designed to use it all up and keep it all used up all the time
for max speed advantage
but don't confuse that with no RAM is available
basically none of the RAM is ever really used up cause it's all virtual and 100% of processes have access to 100% of the RAM 100% of the time.
you are trying to think about it the way the winblows kernel works and forgetting winblows sucks.
