For example, this is what I have on this machine right now: $ free total used free shared buffers cached Mem: 2057836 1958356 99480 0 77972 1437864 -/+ buffers/cache: 442520 1615316 Swap: 2031608 344 2031264 I am using 442520k of memory, but 1962316k is actually occupied by my active processes, plus what amounts to a cache of what I have been doing recently just in case I might want to do it again soon. Linux uses all available ram for that sort of a cache unless it is otherwise required for something else whereupon it is immediately released and given to the process that asked for it. -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com
