If you want to customize PowerShell’s interactive experience with a personalized prompt, you need to modify the $profile variable.
<#Create a new profile (and overwrite one if it already exists):#>
New-Item -type file -force $profile
<#To edit your profile:#>
notepad $profile
<#To see your profile file:#>
Get-ChildItem $profile
<#Once you create a profile script,add a function called Prompt
PowerShell displays the output of this function as your command-line prompt.#>
function Prompt {"PS: Vinith-Server $(get-date)>"}
<#To Immediately reflect the changes made to your profile run#>
. $profile
<#Which would show up like below#>
PS: Vinith-Server 11/13/2012 08:20:36>
<#If you again want to revert back to Default settings, open profile script and remove the entries which you made and save it and close and re-open powershell#>
notepad $profile
<# i see its all back to normal #>
