Defined in:
lib/rubocop/cop/chef/correctness/powershell_file_exists.rb

Overview

Use Ruby’s built-in ‘File.exist?(’C:somefile’)‘ method instead of executing PowerShell’s ‘Test-Path` cmdlet, which takes longer to load.

Examples:


### incorrect
powershell_out('Test-Path "C:\\Program Files\\LAPS\\CSE\\AdmPwd.dll"').stdout.strip == 'True'

### correct
::File.exist?('C:\Program Files\LAPS\CSE\AdmPwd.dll')
