Powershell_exec

Hi @AurimasNav,

You could also use powershell_out mixin. There was already a discussion around this here:

Cant read powershell output to variable

Hi, Problem statement : I want to store powershell cmd output to variable and use the variable in the whole recipe wherever it is required. i tried but not able to do it. kindly help me. powershell_script 'get-python-version' do code 'version = (Get-WmiObject -Class Win32_Product | Select-Object -Property Name | Select-String -Pattern "Python") -replace "@{Name=", "" -replace "}", ""' guard_interpreter :powershell_script end windows_package "#{version}" do action :remove end Rega…

The powershell_out is more expensive approach but since you are shelling out you can parse the stderr and return codes.
Either you choose the powershell_exec or the powershell_out you beed to include their proper mixin:

require "chef/mixin/powershell_out" 
include Chef::Mixin::PowershellOut

script = <<-EOH 
  # your_awsome_ps_script 
EOH 
result = powershell_out(script)

require "chef/mixin/powershell_exec" 
include Chef::Mixin::PowershellExec
