ErrorAction Stop by default in PowerShell scripts

Question

How can I set in a PowerShell script that all the actions have the property ErrorAction set to Stop?

P.S.: Powershell 2.0

Answer 1

Set the $ErrorActionPreference for the script to stop:

$ErrorActionPreference = "Stop"

edit: As ivan-mirchev pointed out, of course this change is not permanet and only active in the runspace where the code is executed. When you open a new Powershell session it will have the default value of $ErrorAction = 'Continue'
