This is great!

I think I did notice one problem: the "swap used" and "swap free" are
reversed.

rainier:~/scripts$ ./free.sh ; swapctl -s ; top | grep "Memory"
             total       used       free    buffers
Mem:        124020     103544      20476          0
Swap:       197564     192316       5248
total: 197568k bytes allocated = 5248k used, 192320k available

        printf("Swap:   %10d %10d %10d\n", totalswap * bpp / 1024,
            swapused * bpp / 1024, (totalswap - swapused) * bpp / 1024);

Thanks for the useful tool (and thanks for the lesson in vmstat).
