After talking with a coworker it seems that "grep" returns a \n after its
output. That was the bugger keeping my initial efforts from working. Grep
was meant for "human consumption". I will need to look into buffio and
scanner as Tamas suggested.

Thank you both for the quick responses. I looked in to
https://github.com/lovoo/ipmi_exporter yesterday and saw the TrimSpace used
as well, but I am still not sure what is adding the '\n' to the commands's
Output().
Tamas, I will have to look into thebuff IO, even if I am not using this for

The input is string, so use strconv.ParseFloat, or ParseInt (will there be
non-integer number of cpus?)
Just trim the LF with strings.TrimSpace.
For production use, leave out the grep and bash, read the output lines directly
with bufio.Scanner.
