Also update $scriptVersion. # # # # The initial version of this script was described in an # # article published in the May 2016 issue of MSDN Magazine. # # https://msdn.microsoft.com/en-us/magazine/mt703436.aspx # # This updated version has one major change: # # The -Service handler in the end has been rewritten to be # # event-driven, with a second thread waiting for control # # messages coming in via a named pipe. # # This allows fixing a bug of the original version, that # # did not stop properly, and left a zombie process behind. # # The drawback is that the new code is significantly longer,# # due to the added PowerShell thread management routines. # # On the other hand, these thread management routines are # # reusable, and will allow building much more powerful # # services. # # # # Dynamically generates a small PSService.exe wrapper # # application, that in turn invokes this PowerShell script. # # # # Some arguments are inspired by Linux' service management # # arguments: -Start, -Stop, -Restart, -Status # # Others are more in the Windows' style: -Setup, -Remove # # # # The actual start and stop operations are done when # # running as SYSTEM, under the control of the SCM (Service # # Control Manager). # # # # To create your own service, make a copy of this file and # # rename it. The file base name becomes the service name. # # Then implement your own service code in the if ($Service) # # {block} at the very end of this file. See the TO DO # # comment there. # # There are global settings below the script param() block. # # They can easily be changed, but the defaults should be # # suitable for most projects. # # # # Service installation and usage: See the dynamic help # # section below, or run: help .\PSService.ps1 -Detailed # # # # History # # 2015-07-10 JFL jf.larvoire@hpe.com created this script. # # 2015-10-13 JFL Made this script completely generic, and added comments # # in the header above. # # 2016-01-02 JFL Moved the Event Log name into new variable $logName. # # Improved comments. # # 2016-01-05 JFL Fixed the StartPending state reporting. # # 2016-03-17 JFL Removed aliases. Added missing explicit argument names. # # 2016-04-16 JFL Moved the official repository on GitHub. # # 2016-04-21 JFL Minor bug fix: New-EventLog did not use variable $logName.# # 2016-05-25 JFL Bug fix: The service task was not properly stopped; Its # # finally block was not executed, and a zombie task often # # remained. Fixed by using a named pipe to send messages # # to the service task. # # 2016-06-05 JFL Finalized the event-driven service handler. # # Fixed the default command setting in PowerShell v2. # # Added a sample -Control option using the new pipe. # # 2016-06-08 JFL Rewrote the pipe handler using PSThreads instead of Jobs. # # 2016-06-09 JFL Finalized the PSThread management routines error handling.# # This finally fixes issue #1. # # 2016-08-22 JFL Fixed issue #3 creating the log and install directories. # # Thanks Nischl. # # 2016-09-06 JFL Fixed issue #4 detecting the System account. Now done in # # a language-independent way. Thanks A Gonzalez. # # 2016-09-19 JFL Fixed issue #5 starting services that begin with a number.# # Added a $ServiceDescription string global setting, and # # use it for the service registration. # # Added comments about Windows event logs limitations. # # 2016-11-17 RBM Fixed issue #6 Mangled hyphen in final Unregister-Event. # # 2017-05-10 CJG Added execution policy bypass flag. # # # ############################################################################### #Requires -version 2 <# .SYNOPSIS A sample Windows service, in a standalone PowerShell script. .DESCRIPTION This script demonstrates how to write a Windows service in pure PowerShell. It dynamically generates a small PSService.exe wrapper, that in turn invokes this PowerShell script again for its start and stop events. .PARAMETER Start Start the service. .PARAMETER Stop Stop the service. .PARAMETER Restart Stop then restart the service. .PARAMETER Status Get the current service status: Not installed / Stopped / Running .PARAMETER Setup Install the service. .PARAMETER Remove Uninstall the service. .PARAMETER Service Run the service in the background. Used internally by the script. Do not use, except for test purposes. .PARAMETER Control Send a control message to the service thread. .PARAMETER Version Display this script version and exit. .EXAMPLE # Setup the service and run it for the first time C:\PS>.\PSService.ps1 -Status Not installed C:\PS>.\PSService.ps1 -Setup C:\PS># At this stage, a copy of PSService.ps1 is present in the path C:\PS>PSService -Status Stopped C:\PS>PSService -Start C:\PS>PSService -Status Running C:\PS># Load the log file in Notepad.exe for review C:\PS>notepad ${ENV:windir}\Logs\PSService.log .EXAMPLE # Stop the service and uninstall it. C:\PS>PSService -Stop C:\PS>PSService -Status Stopped C:\PS>PSService -Remove C:\PS># At this stage, no copy of PSService.ps1 is present in the path anymore C:\PS>.\PSService.ps1 -Status Not installed .EXAMPLE # Send a control message to the service, and verify that it received it.
