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
