How would I run a powershell script that would run on either, the exit
command, or the shell closing. I would want this script to run on every shell close not just for one shell.
Using Register-EngineEvent you can do this:
Register-EngineEvent PowerShell.Exiting –Action { 'Type your Code' }
# Alternatively with hiding the event:
Register-EngineEvent PowerShell.Exiting –Action -SupportEvent { yourExitFunction; }
Get it out of the function and run it in the scriptblock, like this:
Register-EngineEvent PowerShell.Exiting –Action {
$foo = @"

Another option is a try-finally block, which will execute the finally block on error or ctrl-c:
try {
# Main code
} finally {
# Code to run on exit
}
