Uploading a Document using Power Shell Script

To upload a single document to a document library use the following PowerShell script. This is very helpful if we want to automate deployment of files during deployment of code.
The function accepts three parameters:
1. url points to url of the sharepoint site.
2. folder points to Document Library Name
3. Document points to the Path of the file.

function Upload-SPDocument([string]$url, [string]$Folder, [string]$Document) 
{ 
        $SPSite = New-Object Microsoft.SharePoint.SPSite($url) 
        $OpenWeb = $SPSite.OpenWeb() 
        $DocumentName = Split-Path $Document -Leaf 
        $GetFolder = $OpenWeb.GetFolder($Folder) 
        [void]$GetFolder.Files.Add("$Folder/$DocumentName",$((gci $Document).OpenRead()),"") 
        $OpenWeb.Dispose() 
}

Writing to ULS Logs using PowerShell in SharePoint 2010

With SharePoint 2010 the capability to write in ULS Logs has been significantly improved. We can now easily write our own custom message using SharePoint Object model or PowerShell:

Following PowerShell script can be used to write to ULS logs:
$diagSrc = [Microsoft.SharePoint.Administration.SPDiagnosticsServices]::Local
$diacategory = new-object Microsoft.SharePoint.Administration.SPDiagnosticsCategory(“My Category”,
[Microsoft.SharePoint.Administration.TraceSeverity]::Monitorable,
[Microsoft.SharePoint.Administration.EventSeverity]::Error )
$diagSrc.WriteTrace(0, $diacategory, [Microsoft.SharePoint.Administration.TraceSeverity]::Monitorable, “Write your log here” )

If we need to write using SharePoint Object Model following code can be used:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.SharePoint.Administration;

namespace CustomMessageToULSLog
{
    public class ULSLogMessage
    {
        public static void Main(string[] args)
        {
             
            SPDiagnosticsService diagSrc = SPDiagnosticsService.Local;
            diagSrc.WriteTrace( 0, 
                                                    new SPDiagnosticsCategory("Custom category",  TraceSeverity.Monitorable, EventSeverity.Error), 
                                                    TraceSeverity.Monitorable,
                                                    "Writing to the ULS log:  {0}",
                                                    new object[] { "My Custom Message!"});           
            
  
        }
    }
}
