Summary<\/strong>: Microsoft PowerShell MVP, Niklas Goude, talks about using Windows PowerShell to upload a new version of a file to SharePoint.<\/span><\/p>\n

Microsoft Scripting Guy, Ed Wilson, is here. Today Niklas Goude is our guest blogger. You can read more from Niklas in his past Hey, Scripting Guy! Blog posts<\/a>.<\/p>\n

Take it away Niklas…<\/p>\n

In a previous post, Use PowerShell Cmdlets to Manage SharePoint Document Libraries<\/a>, we talked about uploading files to a share in SharePoint 2010. Now we’ll take this a step further and update a minor or a major version of an existing document.<\/span><\/p>\n

Here’s a quick recap of the code used to upload the file:<\/p>\n

# Add the Snapin
Add-PSSnapin Microsoft.SharePoint.PowerShell<\/p>\n

# Retrieve specific Site
$spWeb = Get-SPWeb http:\/\/SP01<\/p>\n

# Create instance of Folder
$spFolder = $spWeb.GetFolder(“Shared Documents”)<\/p>\n

# Get the file on Disk that we want to upload
$file = Get-Item C:\\Documents\\MyDoc.docx<\/p>\n

# upload the file.
$spFolder.Files.Add(“Shared Documents\/MyDoc.docx”,$file.OpenRead(),$false)<\/p>\n

What we’ve done so far is to upload a single document to a document library in SharePoint 2010. The file used in this example is stored on drive C: <\/p>\n

\"Image<\/a><\/p>\n

  <\/p>\n

The document contains a single line:<\/p>\n

\"Image<\/a><\/p>\n

 <\/p>\n

After we run the Windows PowerShell code, the document gets uploaded to a document library in SharePoint 2010.<\/p>\n

\"Image<\/a><\/p>\n

 <\/p>\n

We can check the versioning for the document by clicking Version History in SharePoint:<\/p>\n

\"Image<\/a><\/p>\n

 <\/p>\n

We’ll see that the version number is set to 0.1:<\/p>\n

\"Image<\/a><\/p>\n

 <\/p>\n

Now, let’s open the file that is stored on drive C and modify it:<\/p>\n

\"Image<\/a><\/p>\n

Back in Windows PowerShell, we use SPFileCollection<\/strong> to pick up the document we just uploaded. In this example, we are going to filter out the document where the name is equal to MyDoc.docx by using the Where-Object<\/strong> cmdlet.<\/p>\n

# Retrieve specific Site
$spWeb = Get-SPWeb http:\/\/SP01<\/p>\n

# Create instance of Folder
$spFolder = $spWeb.GetFolder(“Shared Documents”)<\/p>\n

# Retrieve a Specific File.
$spFile = $spFolder.Files | Where-Object { $_.Name -eq “MyDoc.docx” }<\/p>\n

We pick up the file because we want to use some of its properties for the new version that we want to upload. When we upload a new version of the document, we still use the Add<\/strong> method that is provided by the Microsoft.SharePoint.SPFileCollection, but with a different overload definition. Here’s the definition on MSDN: <\/span>SPFileCollection.Add method (String, Stream, SPUser, SPUser, DateTime, DateTime)<\/a>.<\/span><\/p>\n

The parameters we want to use are: urlOfFile<\/strong>, File<\/strong>, CreatedBy<\/strong>, ModifiedBy<\/strong>, TimeCreated<\/strong>, and TimeLastModified<\/strong>.<\/p>\n

We can get the following values from the existing document in SharePoint 2010: UrlOfFile<\/strong>, CreatedBy<\/strong>, ModifiedBy<\/strong>, and TimeCreated<\/strong>. We can get File<\/strong> by using Get-Item<\/strong>, and we can get TimeLastModified<\/strong> by simply using Get-Date<\/strong>.<\/p>\n

First, let’s get the modified MyDoc.docx from drive C:<\/p>\n

$file = Get-Item C:\\Documents\\MyDoc.docx<\/p>\n

Next we run the method:<\/p>\n

$newVersion = $spFolder.Files.Add($spFile.Name, $file.OpenRead(), $spFile.Author, $spFile.ModifiedBy, $spFile.TimeCreated, (Get-Date))<\/p>\n

If we open the SharePoint document library again, we’ll see that we have a new minor version of our document, .02.<\/p>\n

\"Image<\/a><\/p>\n

And finally, if we want to add the modified document as a major version, we use the Publish<\/strong> method:<\/p>\n

$newVersion.Publish(“”)<\/p>\n

Now we have a new major version, 1.0, instead.<\/p>\n
