Need suggestion about grep and CPU usage
guys i need suggestion about how to grep cpu usage and then compare it
example :
if cpu usage <= 40% then print normal and how much cpu usage is
or cpu usage between 40%-65% print normal and much cpu usage is

i've tried like this one but got error

Code:
DOMAIN=`uname -n`
cpuload="/users/daniel/cpuload.txt"
usage=`top $DOMAIN | grep idle` >> $cpuload`
usage2=`$cpuload | awk '{print $3}'`
for DOMAIN in ${usage};
do 
 $usage2
 {  
   if[$usage2 <= 40%]; then 
    echo "$DOMAIN Normal $usage2"
   elif [$usage2 -ge 40% && $usage2 -lt 65%] 
    then echo "$DOMAIN Warning $usage2"      
   elif$usage2 -ge 65% && $usage -lt 70%
    then echo "$DOMAIN Major $usage2"
   else         
    echo "$DOMAIN Critical $usage2"   
   fi
 } 
done


thanks before

cpufreq-set

cpufreq-set(1)															    cpufreq-set(1)

NAME

       cpufreq-set - A small tool which allows to modify cpufreq settings.

SYNTAX

       cpufreq-set [options]

DESCRIPTION

       cpufreq-set  allows you to modify cpufreq settings without having to type e.g. "/sys/devices/system/cpu/cpu0/cpufreq/scaling_set_speed" all
       the time.

OPTIONS

       -c --cpu <CPU>
	      number of CPU where cpufreq settings shall be modified.

       -d --min <FREQ>
	      new minimum CPU frequency the governor may select.

       -u --max <FREQ>
	      new maximum CPU frequency the governor may select.

       -g --governor <GOV>
	      new cpufreq governor.

       -f --freq <FREQ>
	      specific frequency to be set. Requires userspace governor to be available and loaded.

       -r --related
	      modify all hardware-related CPUs at the same time

       -h --help
	      Prints out the help screen.

REMARKS

       Omitting the -c or --cpu argument is equivalent to setting it to zero.

       The -f FREQ, --freq FREQ parameter cannot be combined with any other parameter except the -c CPU, --cpu CPU parameter.

       FREQuencies can be passed in Hz, kHz (default), MHz, GHz, or THz by postfixing the value with the wanted unit name, without any space (fre-
       quency in kHz =^ Hz * 0.001 =^ MHz * 1000 =^ GHz * 1000000).

       On Linux kernels up to 2.6.29, the -r or --related parameter is ignored.

FILES

       /sys/devices/system/cpu/cpu*/cpufreq/
       /proc/cpufreq (deprecated)
