Terminating a script in Powershell

Question

I've been looking for a way to terminate a Powershell (PS1) script when an unrecoverable error occurs within a function. For example:

function foo() {
    # Do stuff that causes an error
    $host.Exit()
}

Of course there's no such thing as $host.Exit(). There is $host.SetShouldExit() but this actually closes the console window, which is not what I want. What I need is something equivalent to Python's sys.exit() that will simply stop execution of the current script without further adieu.

Edit: Yeah, it's just exit. Duh.

Answer 1

What about the 'Exit' command?

Answer 2

May be it is better to use "trap". A PowerShell trap specifies a codeblock to run when a terminating or error occurs. Type
