Powershell scripting
Variables
Variables are declared like this
$test = "something"
Execute scripts
So for security reasons the default policy for executing scripts is Restricted. Here are the different script-policies.
Restricted: PowerShell won't run any scripts. This is PowerShell's default execution policy.
AllSigned: PowerShell will only run scripts that are signed with a digital signature. If you run a script signed by a publisher PowerShell hasn't seen before, PowerShell will ask whether you trust the script's publisher.
RemoteSigned: PowerShell won't run scripts downloaded from the Internet unless they have a digital signature, but scripts not downloaded from the Internet will run without prompting. If a script has a digital signature, PowerShell will prompt you before it runs a script from a publisher it hasn't seen before.
Unrestricted: PowerShell ignores digital signatures but will still prompt you before running a script downloaded from the Internet.

So if we want to run script myscript.ps1 we have to set the execution-policy.
First let's check what execution-policy we currently have:
Get-ExecutionPolicy
Then we can set the execution policy like this
set-ExecutionPolicy unrestricted
or
Set-ExecutionPolicy Bypass
Generate Multiple Lines to print to Screen
Use Here-Strings
You can use here-strings to declare blocks of text. They’re declared just like regular strings except they have an @ on each end. Instead of being limited to one line, you can declare an entire block or a multiple line string. Here-strings are also useful for making a string composed of the text to execute a command. Examples:
$String1 = @"
Get-ChildItem c:\temp
"@
$String2 = @"
This is some
multiple line
text!
"@
Write-Host @"
I am writing cool
things to the screen
Arent I cool
"@
