Question & Answer :
I’ve been trying for a manner to terminate a PowerShell (PS1) book once an unrecoverable mistake happens inside a relation. For illustration:

relation foo() { # Bash material that causes an mistake $adult.Exit() }

Of class location’s nary specified happening arsenic $adult.Exit(). Location is $adult.SetShouldExit(), however this really closes the console framework, which is not what I privation. What I demand is thing equal to Python’s sys.exit() that volition merely halt execution of the actual book with out additional ado.

Edit: Yea, it’s conscionable exit.

I recognize this is an aged station however I discovery myself coming backmost to this thread a batch arsenic it is 1 of the apical hunt outcomes once looking out for this subject. Nevertheless, I ever permission much confused past once I got here owed to the conflicting accusation. Finally I ever person to execute my ain exams to fig it retired. Truthful this clip I volition station my findings.

TL;DR About group volition privation to usage Exit to terminate a moving scripts. Nevertheless, if your book is simply declaring features to future beryllium utilized successful a ammunition, past you volition privation to usage Instrument successful the definitions of stated capabilities.

Exit vs Instrument vs Interruption

Interruption: This volition interruption retired of loops and control circumstances.

If you call Interruption wrong a loop that is nested wrong a loop it volition lone interruption retired of the loop it was referred to as successful.

Location is besides an absorbing characteristic of Interruption wherever you tin prefix a loop with a description and past you tin interruption retired of that labeled loop equal if the Interruption bid is known as inside respective nested teams inside that labeled loop.
