I have SunOS 5.10 sparc server. I want to calculate buffer memory. I can easily find this in Linux using /usr/bin/free command. 

             total       used       free     shared    buffers     cached
Mem:      8004388    7427228     577160          0     472196    3336544
-/+ buffers/cache:   3618488    4385900
Swap:     11534628          0   11534628

Can anyone please suggest me if there is any equivalent command in SunOS. It would be better if anyone can give me any Perl script to find the same in below format.
