> When I check the output of Ubuntu's 13.04 top (top -v = procps-ng version
> 3.3.3), it's formatted like this:
> raring# top -b -n 1|grep Cpu\(s\):
> %Cpu(s): 0.2 us, 0.2 sy, 0.0 ni, 99.5 id, 0.1 wa, 0.0 hi, 0.0 si, 0.0
> st
> While on Ubuntu 12.04 (top -v = procps version 3.2.8) it looks like this:
> precise# top -b -n 1|grep Cpu\(s\):
> Cpu(s): 0.3%us, 0.1%sy, 0.0%ni, 99.6%id, 0.1%wa, 0.0%hi, 0.0%si, 0.0%st
> So I believe it is better to split the string on a comma (,) than using the
> percentage (%).
