The file don't exist when the only_if run  at compile time.  Run your powershell resource at compile time with end.run_action(:create) (see the default action I'm unsure)

At all it sounds you may be on the wrong way to achieve your goal, but without more details it's hard to give advices.

Ok I made a little more progress..

But the problem is that the order is not correct, the file doesn’t exist when reportback runs..?



powershell_script 'filever' do
code <<-EOH
[System.Diagnostics.FileVersionInfo]::GetVersionInfo("C:\\Program Files\\Internet Explorer\\iexplore.exe").FileVersion > C:\\windows\\temp\\fileversion.txt
EOH
end

execute "reportback" do
  command "echo 1"
  node.normal[:ixserver][:Version_Installed] = File.read("C:\\windows\\temp\\fileversion.txt")
  only_if {  ::File.exists?("C:\\windows\\temp\\fileversion.txt") }
end

Subject: [chef] Windows and powershell_out

Hi guys

I have managed to properly confuse myself well and truly!

Scenario: Basic Chef installation, server is Ubuntu 12.04, client is windows 2012 server.

What I want to do: Read the "version" property of a file into an attribute of a node. 

What I've tried: You can see my attempt below. It seems that the PowerShellOut "mixin" is not available, but I'm too scared to add the windows and powershell cookbooks to my collection, because I understand that they are already included in the latest chef. So now I'm stuck! Help!!!

The powershell code below runs and creates the text file fine, but how do I get the value from the text file into the attribute?

The Code:

powershell_script 'filever' do
code <<-EOH
[System.Diagnostics.FileVersionInfo]::GetVersionInfo("C:\\Program Files\\Internet Explorer\\iexplore.exe").FileVersion > C:\\windows\\temp\\fileversion.txt
get-content -Path  C:\\windows\\temp\\fileversion.txt
EOH
end

powershell_script 'filever2' do
  ::Chef::Recipe.send(:include, Chef::Mixin::PowershellOut)
  #include Chef::Mixin::PowershellOut
  node.normal[:ixserver][:Hello] = powershell_out("echo hello") end


I'm hoping you guys can help..

 Many regards
Iain
