Hi Wilson


May be try the -l options ( man ps ) but then the better way to find the cpu usage is to use may be top or glance.

Hi

the ps command has lots of columns it can display including Percentage of CPU time used by process The column header is %CPU and the option to use is pcpu

ps -flPpcpu

Use the -l switch to ps (i.e. ps -elf). It will give a rough idea of CPU utilized in the column labeled "C"

The man page specifies this as "Processor utilization for scheduling"

Hi,

Use glance or top and from there you can find out easily.

You can even find out which processes are using the CPU and for how much time.

Hi Wilson,

Use top to see the process cpu usage.

You can also use ps like this,

export UNIX95=XPG4
ps -o pcpu

Hope this helps.

Hello

Try using UNIX95 option within ps. The following command would give you the list of top ten cpu consumed process
Pleas note that there is space after equalto sign
UNIX95= ps -e -o "pcpu vsz ruser pid stime time state args" | sort -rn |head -10

Goodluck,
