How to get the memory using status ?

Like "statfs" to get the infomation about the file system, have any command to get information about the memory information or using status ?

Thanks.

I got another command can show the memory using "free"
but the memory details display from these command have some different.

which is the memory using of the system ?

Code:

[test@localhost ~]$ free
             total       used       free     shared    buffers     cached
Mem:        255636     245740       9896          0       4740      70984

On Linux you may use sysinfo(2) as well.
