Hi I want to create a list of percentages but the shell script is bugging me.
If if I want to resolve the percentage of the quota used I get 0 because the schell script rounds by default.
Example
w1=860
w2=1024
w3=$((($w1/$w2)*100))
Echo $w3 gives 0
When I divide w1 by w2 the result is 0,83!
Can somebody help me?
w3=$( echo "scale=6; ( $w1 / $w2 ) * 100" | bc )
some scale
c=`echo "scale=6; $a / $b" | bc`
Hi when i use w3=$( echo "scale=6; ( $w1 / $w2 ) * 100" | bc )
I get the error Command not found
check whether the directory in which bc lives is in the $PATH
usually it should be as
/usr/bin/bc
bc is not located in the usr/bin folder. Is there an easy way to locate the command so I can put it in the path?
Could you please let us know the operating system that you are using ? 
Linux Version 2.4.20-28.5505.EMC
(gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-98))
Hi,
I quick search on the internet gives that on REDHAT 7.1 the bc package is not installed by default. This could be the cause that bc is not working for me. I am not allowed to install this software so I need an other way... can u help me?
Regards,
Michel
check hegemaro's post for division without using bc
or
w3=$( echo $w1 $w2 | awk ' { printf("%.2f", $1 / $2 * 100 ) } ' )
That works... thanks again!! you are a lifesaver
I was to quick with my response... I do have a minor problem.. I am getting the command not Found. This is the trace of the code
++ USERID=5003

++ PERCENTAGE=

Thanks... I have everything working at the moment!
