First you need the processes and the information you want, then you have to format the output.

On HP-UX I use:

Code:
   export UNIX95=1
   ps -efH -o pcpu,user,nice,cpu,pid,args |  grep -vE "^ *0\.0|defunct|CPU|high_cpu|init" >$LOG_FILE1

Then you need to 'sort' the information:
Code:
sort -T $SORT_DIR -r -n -k 1

And if you only want the top 10, use
Code:
head

Finally:
Ex:
Code:
high_cpu

CPU    User       Nice   CPU  PID        Command

systemd-rc-local-generator

SYSTEMD-RC-LOCAL-GENERATOR(8)				    systemd-rc-local-generator				     SYSTEMD-RC-LOCAL-GENERATOR(8)

NAME

       systemd-rc-local-generator - Compatibility generator for starting /etc/rc.local and /usr/sbin/halt.local during boot and shutdown

SYNOPSIS

       /lib/systemd/system-generators/systemd-rc-local-generator

DESCRIPTION

       systemd-rc-local-generator is a generator that checks whether /etc/rc.local exists and is executable, and if it is pulls the
       rc-local.service unit into the boot process. This unit is responsible for running this script during late boot. Note that the script will
       be run with slightly different semantics than the original System V version, which was run "last" in the boot process, which is a concept
       that does not translate to systemd. The script is run after network.target, but in parallel with most other regular system services.

       systemd-rc-local-generator also checks whether /usr/sbin/halt.local exists and is executable, and if it is pulls the halt-local.service
       unit into the shutdown process. This unit is responsible for running this script during later shutdown.

       Support for both /etc/rc.local and /usr/sbin/halt.local is provided for compatibility with specific System V systems only. However, it is
       strongly recommended to avoid making use of these scripts today, and instead provide proper unit files with appropriate dependencies for
       any scripts to run during the boot or shutdown processes.

       systemd-rc-local-generator implements systemd.generator(7).
