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() {
    #         


        

Answer 1

Terminates this process and gives the underlying operating system the specified exit code.

https://msdn.microsoft.com/en-us/library/system.environment.exit%28v=vs.110%29.aspx

[Environment]::Exit(1)

This will allow you to exit with a specific exit code, that can be picked up from the caller.
