How to restrict awk math output to 2 decimal places
0
My Command is below and its print Free CPU and Used CPU below format.
I want to restrict awk output to 2 decimal place.
grep 'cpu ' /proc/stat | awk '{usage=($2+$4)*100/($2+$4+$5)} {free=($5)*100/($2+$3+$4+$5)} END {print "Used Cpu:",usage "%"} {print "Free Cpu:",free "%"}'
Output :
Free Cpu: 98.9588%
Used Cpu: 1.04125%
Desired output :
Free Cpu: 98.95%
Used Cpu: 1.04%

Note, your END block only prints "Used Cpu" -- the block that prints "Free Cpu" is not in the END block, and wil therefore print for each line of input.

A bit of code review:
- awk can do what grep does, so you don't need the pipeline
- add newlines to the awk code for reability
For example:
awk '$1 == "cpu" {
printf "Used Cpu: %5.2f%%n", 100*($2+$4)/($2+$4+$5)
printf "Free Cpu: %5.2f%%n", 100*$5/($2+$3+$4+$5)
}' /proc/stat
which outputs the nicely aligned
Used Cpu: 5.34%
Free Cpu: 94.63%

An alternative way is to define an output format OFMT="%5.2f%%" to format all numeric output:
$ awk -v OFMT="%5.2f%%" '
$1 == "cpu" {
print( "Used Cpu: ", 100*($2+$4)/($2+$4+$5) )
print( "Free Cpu: ", 100*$5/($2+$3+$4+$5) )
}
' /proc/stat
