The abbreviated answer is to use the "free" command, which gives a simple and usable result. But, most operating systems, including linux, aren't limited by the amount of RAM in the system, but rather the amount of swap space (a chunk of your hard drive dedicated to this purpose). The output of the "free" command is intuitive once it's understood; at first it looks confusing because linux will use up to all available memory to cache disk file blocks, and it will simply begin to give those up when a running program demands RAM for immediate use. Is there a particular problem that you're trying to address that may be tied to the available RAM (for various values of "available")?
