Getting load average as variables

I'm setting up a logging script with Ruby and am having some difficulties with getting the load averages as a variable. I'm using:

uptime | awk '{print $10}'

to get the current 1 minute time stamp, but I'm having trouble getting it without a trailing comma. I could edit the string later, but that seems less efficient. Is there an edit that will simply remove the , from the return?

In the end, it also works through /proc/loadavg, but the usage is a little more idiomatic, so I thought I'd mention the sys-cpu Gem (which existed even in 2013 :)) as well:

gem install sys-cpu

require 'sys-cpu'
puts Sys::CPU.load_avg

... which will give you a nice array: [0.72, 1.14, 1.11].

How about:

cut -f 1 -d " " /proc/loadavg

The uptime command reads /proc/loadavg and then adds the commas.
