module Chef::Mixin::PowershellOut
Public Instance Methods
Run a command under powershell with the same API as shell_out. The options hash is extended to take an “architecture” flag which can be set to :i386 or :x86_64 to force the windows architecture.
@param script [String] script to run @param options [Hash] options hash @return [Mixlib::Shellout] mixlib-shellout object
# File lib/chef/mixin/powershell_out.rb, line 33 def powershell_out(*command_args) script = command_args.first options = command_args.last.is_a?(Hash) ? command_args.last : nil run_command_with_os_architecture(script, options) end
Run a command under powershell with the same API as shell_out! (raises exceptions on errors)
@param script [String] script to run @param options [Hash] options hash @return [Mixlib::Shellout] mixlib-shellout object
# File lib/chef/mixin/powershell_out.rb, line 46 def powershell_out!(*command_args) cmd = powershell_out(*command_args) cmd.error! cmd end
Private Instance Methods
Helper to build a powershell command around the script to run.

Helper function to run shell_out and wrap it with the correct flags to possibly disable WOW64 redirection (which we often need because chef-client runs as a 32-bit app on 64-bit windows).
@param script [String] script to run @param options [Hash] options hash @return [Mixlib::Shellout] mixlib-shellout object
