Windows PowerShell Exit Codes

 

PSMDTAG:FAQ: How can my script control the PowerShell exit code?

Answers:

1. A normal termination will set the exitcode to 0
2. An uncaught THROW will set the exitcode to 1
3. The EXIT statement will stop the process and set the exitcode to whatever is specified.
