    I am new in Powershell. so i am messing with variable ... 

    PS C:\WINDOWS\system32> Get-Content 'C:\Users\Administrator\Desktop\Demo.txt'
    User1
    User2
    User3

    PS C:\WINDOWS\system32>

    after that ..

    PS C:\WINDOWS\system32> $User = Get-Content 'C:\Users\Administrator\Desktop\Demo.txt'
    PS C:\WINDOWS\system32> $User
    User1
    User2
    User3
    PS C:\WINDOWS\system32>

    Working Fine ....

    But if I update that Demo.txt file, it would not replicate my variable .

    Is that meant to work like that or am i missing something ?

    If you update the file then you need to run the Get-Content command again for the variable to be updated.

    $ContentOutput = Get-Content 'c:\Users\Administrator\Desktop\Demo.txt'
    $ContentOutput

    In the next version of computers we will using quantum computing to allow variables to know when a remote file is being changed.  I hear they can do this with quantum particles.  A particle always knows what its twin I up to.

    I think you're a little confused. The first command "$user = get-content #PATH" put the value into the variable and the second line "$user" simply writes the value of the variable to the console.

    If you update the file then you need to run the Get-Content command again for the variable to be updated.

    $ContentOutput = Get-Content 'c:\Users\Administrator\Desktop\Demo.txt' | Write-Host

    This command does nothing.  You cannot use Write-Host in a pipeline as it kills the pipeline.
