I cut/pasted below a script I used to use a long time ago to check the available memory on HP and SGI.


#!/bin/ksh

TMPFL=/tmp/showsys.tmp;touch $TMPFL
SCRIPTDIR=/scripts
case `uname -s` in
HP-UX*) #Machine type is HP HPUX
if [ `uname -m` = "ia64" ]; then
HPUX=/stand/vmunix
MAJORREV=$(uname -r | cut -f2 -d .)
if [ $MAJORREV -ge "11.0" ]; then MYSYMBOL="phys_mem_pages"; else MYSYMBOL="physmem"; fi
MEM=$(echo "${MYSYMBOL}" | adb $HPUX /dev/kmem | grep "${MYSYMBOL}: *." | awk '{printf "%.0fMB\n",$2/256}')
MHZ=$(echo itick_per_tick | adb $HPUX /dev/kmem | tail -1 | awk '{print $2/10000}')
else
HPUX=/stand/vmunix
MAJORREV=$(uname -r | cut -f2 -d .)
if [ $MAJORREV -ge "11.0" ]; then MYSYMBOL="phys_mem_pages"; else MYSYMBOL="physmem"; fi
MEM=$(echo "${MYSYMBOL}/D" | adb $HPUX /dev/kmem | grep "${MYSYMBOL}: *." | awk '{printf "%.0f MB\n",$2/256}')
