Function Add-IniComment { <# .Synopsis Comments out specified content of an INI file .Description Comments out specified keys in all sections or certain sections. The ini source can be specified by a file or piped in by the result of Get-IniContent. The modified content is returned as a ordered dictionary hashtable and can be piped to a file with Out-IniFile. .Notes Author : Sean Seymour <seanjseymour@gmail.com> based on work by Oliver Lipkau <oliver@lipkau.net> Source : https://github.com/lipkau/PsIni http://gallery.technet.microsoft.com/scriptcenter/ea40c1ef-c856-434b-b8fb-ebd7a76e8d91 Version : 1.0.0 - 2016/08/18 - SS - Initial release : 1.0.1 - 2016/12/29 - SS - Removed need for delimiters by making Sections and Keys string arrays. #Requires -Version 2.0 .Inputs System.String System.Collections.IDictionary .Outputs System.Collections.Specialized.OrderedDictionary .Example $ini = Add-IniComment -FilePath "C:\myinifile.ini" -Sections 'Printers' -Keys 'Headers','Footers' ----------- Description Reads in the INI File c:\myinifile.ini, comments out any keys named 'Headers' or 'Footers' in the [Printers] section, and saves the modified ini to $ini. .Example Add-IniComment -FilePath "C:\myinifile.ini" -Sections 'Terminals','Monitors' -Keys 'Updated' | Out-IniFile "C:\myinifile.ini" -Force ----------- Description Reads in the INI File c:\myinifile.ini and comments out any keys named 'Updated' in the [Terminals] and [Monitors] sections. The ini is then piped to Out-IniFile to write the INI File to c:\myinifile.ini. If the file is already present it will be overwritten. .Example Get-IniContent "C:\myinifile.ini" | Add-IniComment -Keys 'Headers' | Out-IniFile "C:\myinifile.ini" -Force ----------- Description Reads in the INI File c:\myinifile.ini using Get-IniContent, which is then piped to Add-IniComment to comment out any 'Headers' keys in any section. The ini is then piped to Out-IniFile to write the INI File to c:\myinifile.ini. If the file is already present it will be overwritten. .Example Get-IniContent "C:\myinifile.ini" | Add-IniComment -Keys 'Updated' -Sections '_' | Out-IniFile "C:\myinifile.ini" -Force ----------- Description Reads in the INI File c:\myinifile.ini using Get-IniContent, which is then piped to Add-IniComment to comment out any 'Updated' keys that are orphaned, i.e. not specifically in a section. The ini is then piped to Out-IniFile to write the INI File to c:\myinifile.ini. .Link Get-IniContent Out-IniFile #> [CmdletBinding(DefaultParameterSetName = "File")] [OutputType( [System.Collections.Specialized.OrderedDictionary] )] Param ( # Specifies the path to the input file.
