Powershell Quick Start

Get-Alias- complete list of available aliases

Get-Command - that returns a list of all the PowerShell cmdlets available to you

Format-List : is a cmdlet that takes information passed to it and then outputs that information in list view (that is, property values are displayed on separate lines rather than as columns in a table).

Eg:PS C:\scripts> Get-Command | Format-List

Format-Table : cmdlet can take pretty much any information and display it as a table rather than a list.

set-location c:\Windows

Get-ChildItem C:\Scripts –recurse

Set-ExecutionPolicy RemoteSigned

To run scripts from within Windows PowerShell you will need to change your security settings; by default, PowerShell only runs scripts signed by a trusted authority.

Get-Process

To get information about the properties and methods of an object retrieve an instance of that object and then “pipe” the object to the Get-Member cmdlet. For example, this command returns the properties and methods available when working with processes:  eg Get-Process | Get-Member

Get-Process 

To work with or display specified properties of a collection, pipe the returned results to the Select-Object cmdlet:

Eg Get-Process | Select-Object Name, Company

Where-Object {$_.Length -gt 200KB} | Sort-Object Length

To filter and sort objects . Sort-Object should typically appear on the right-hand side of a pipeline.

Eg1:

Get-ChildItem C:\Scripts | Where-Object {$_.Length -gt 200KB} | Sort-Object Length

eg2: Get-Service | Sort-Object Status | Format-Table

eg:3: $a = (Get-Process | Sort-Object ID)

You have a variable $a that contains a collection of data. You can sort that data, and sidestep the pipeline altogether, by using a command like this: eg: Sort-Object -inputobject $a

Excellent JQuery FAQ and live explanations

Get Username for logged in user Asp.net

The below is when using Windows Authentication using ASp.net

In ASP.NET, please use User.Identity.Name to get the logon user. User.Identity.Name might be empty if Anonymous Authentication is enabled in IIS.
http://msdn2.microsoft.com/en-us/library/system.web.httpcontext.user.aspx
Here is the logical to check if the identity is available.

VB.NET
' Gets the name if authenticated.

If User.Identity.IsAuthenticated Then

    Label1.Text = User.Identity.Name

Else

    Label1.Text = "No user identity available."

End If

C#

' Gets the name if authenticated.

if (User.Identity.IsAuthenticated)

    Label1.Text = User.Identity.Name;

else

    Label1.Text = "No user identity available.";

Environment.UserName is the running thread identity. If you have enabled Impersonation as Mark said, you can find out the returning result will be different. However this requires ASP.NET Impersionation. If you don't need ASP.NET Impersonation and dealing with the thread identity, you can ignore Environment.UserName if and just use User.Identity.Name.

Alternate ways to get username are are

.Context.Request.LogonUserIdentity.Name

Request.LogonUserIdentity.Name
