Summary<\/b>: Microsoft Scripting Guy, Ed Wilson, talks about using Windows PowerShell to update Windows PowerShell Help on remote servers.<\/span><\/p>\n

Microsoft Scripting Guy, Ed Wilson, is here. One of the great things about any version of Windows PowerShell is the Help that comes with the product. Having access to Get-Help<\/b> is great whether I am working on a server or a workstation. I will admit that even having worked with Windows PowerShell as long as I have, I do not remember every cmdlet, every nuance, every switch and parameter available. I don’t think anyone does.<\/p>\n

This greatness is actually a double-edged sword. Beginning with Windows PowerShell 3.0, the Help is not installed by default; and therefore, it must be updated. This is also a good thing because it helps ensure that the Help is up-to-date, complete, and accurate.<\/p>\n

A problem occurs, however, when I have servers that do not have access to the Internet. How do I deal with that situation?<\/p>\n

It is tempting to not have any Help on the systems at all. After all, I am pretty good with Windows PowerShell, so I can more than likely do what I need to do. But it is much better if I do have access to Help on the servers. So what do I do? Luckily, Windows PowerShell has an answer. The answer is Save-Help<\/b> and Update-Help<\/b>.<\/p>\n

Download Help<\/h2>\n

The first thing I need to do is to download the Help files. This means I need a computer that has access to the Internet. In addition, if I want to get Help for a specific module, it is easiest if I have that module installed because then I will automatically get the Help for that module.<\/p>\n

It makes sense for me to download the files directly to a shared location. The first thing I do is delete any files that may be in my shared Help location. I do this to keep from running to issues with trying to overwrite existing files. Here is the command I use to delete the files:<\/p>\n

Remove-Item C:\\Shared\\UpdateHelp -Include *.* -Recurse<\/p>\n

Now I download the Help files for all of the modules installed on my server. Here is the command I use:<\/p>\n

Save-Help -Module * -DestinationPath \\\\dc1\\share\\UpdateHelp<\/p>\n

After I download the Help files, I can go to the folder and see what (if anything) happened. Here, I see the Help files:<\/p>\n

Install the Help files on remote servers<\/h2>\n

Now I can install the Help files on my remote servers. To do this, I use Windows PowerShell remoting to run the Update-Help<\/b> cmdlet on each of the remote servers. When I call Update-Help<\/b>, I specify the path to my Help shared folder. Here is the command I use from my workstation:<\/p>\n

Invoke-Command -ComputerName S1, S2 { Update-help -SourcePath \\\\dc1\\Share\\UpdateHelp -force }<\/p>\n

I did not need to specify credentials because I am signed in with an account that has Admin rights on the remote servers. If I was not signed in as an Admin, I would need to specify the –Credential<\/b> parameter and supply credentials for the command.<\/p>\n

I use the Invoke-Command<\/b> cmdlet again to see if I did, in fact, get the Help files updated. Here is the command I use:<\/p>\n

Invoke-Command -ComputerName S1, S2 { get-help get-help }<\/p>\n

This command is simple, and I simply check to see if I have the Help files for Get-Help<\/b>. Previously, I did not—now I do. Sweet! It works.<\/p>\n

Now I can use the Task Scheduler to run these commands on my various systems, and keep Help automatically updated. Because all of these commands are one-liners, it is really easy to do. Sweet.<\/p>\n

I invite you to follow me on Twitter<\/a> and Facebook<\/a>. If you have any questions, send email to me at scripter@microsoft.com<\/a>, or post your questions on the Official Scripting Guys Forum<\/a>. See you tomorrow. Until then, peace.<\/p>\n
