I am not sure of the features of awk on HP-UX, but on Linux, you can do
all the processing with a single invocation of awk and swapinfo:

/usr/sbin/swapinfo | awk '/^memory/ {tot=$2/1024;free=$4/1024} END
{printf "Total: %d\nFree: %d\n",tot,free}'

It would be useful to know if this version works on HP-UX.
