Hi,
Is there a way of determining the cpu clock speed via the command line.

many thx

yes... use this:

#!/usr/bin/ksh
BOLD="`tput smso`"
NORMAL="`tput rmso`"
cpu=$(echo itick_per_tick/D | adb /stand/vmunix /dev/kmem | sed -n '2p' | awk '{print $2}' | sed 's/0000$//g')
cpu_num=$(grep -i proc /var/adm/syslog/syslog.log | wc -l)
echo "`hostname` has ${BOLD}$cpu_num${NORMAL} processors at ${BOLD}$cpu${NORMAL} Mhz"

to get the speed of the CPU:
echo "itick_per_usec/D" | adb /stand/vmunix /dev/kmem

Hi,

Have a look at the following thread :

I use the following little script:

HPUX=/stand/vmunix

MHZ=$(echo itick_per_tick/D | adb -k $HPUX /dev/kmem | tail -1 | awk '{print $2/10000}')
echo $MHZ

Yes - I use this script called hpmem.

It gives you some additional settings as well....

Here's a sample output:

maybe you can just use the "model" command, usually, the last 2 digital of the output indicates the CPU speed. e.g

9000/800/L2000-44 is 440MHZ
9000/800/L1000-5X is 540MHZ

Hello!

Check this:
echo "itick_per_tick/D" | adb -k /stand/vmunix /dev/kmem | tail -1

The kernel file must be set correctly, normall it is /stand/vmunix!
You can get the cpu clock speed in MHz by:
#echo itick_per_usec /D |adb -k /stand/vmunix /dev/kmem|tail -1|awk '{print $2}'
540 (example)
