7.74 How can I determine how much memory there is in my HP-UX system?

Here are three methods to determine the amount of physical memory
on your system (while logged on as superuser):
  1. If the diagnostic messages are still in the system buffer since
     the last reboot, the following will give the total kbytes:
        dmesg | awk '/Physical:/ && /Kbytes/ {print $2}'

  2. As of 10.X, the following SAM command will show memory in Mb:
        /usr/sam/lbin/getmem

  3. It's slow, but the following method will give the total bytes:
        wc -c /dev/mem
