What is equivalent of Linux's 'free' command on FreeBSD v8.1

What is equivalent of Linux's 'free' command on FreeBSD v8.1?

I am calling 'free' from my application and reporting the results in my application's log file. What would be the replacement when porting to FreeBSD v8.1?

Here is a sample run of 'free' on Linux:

[centos4x32 ~] free
total used free shared buffers cached
Mem: 774452 733044 41408 0 98040 328880
-/+ buffers/cache: 306124 468328
Swap: 2031608 224 2031384

Answer
  • vmstat has default output which is similar in nature and takes many options that give extremely detailed information, eg vmstat -m
  • swapinfo would cover the swap part
  • top -d1 causes top to print one screen and exit, and the banner is very similar to free
