run_noninteractive(command) click to toggle source

Runs command via shell_out with magic environment to disable interactive prompts. Command is run with default localization rather than forcing locale to “C”, so command output may not be stable.

FIXME: This should be “LC_ALL” => “en_US.UTF-8” in order to stabilize the output and get UTF-8

# File lib/chef/provider/package/dpkg.rb, line 142
def run_noninteractive(command)
  shell_out!(command, :env => { "DEBIAN_FRONTEND" => "noninteractive", "LC_ALL" => nil })
