PowerShell Exit Script- How to Terminate Script

PowerShell Exit function terminates a script. Using the Exit keyword in PowerShell can terminate a console or script in scope. It stops PowerShell script.

Using Exit cmdlet in PowerShell, you can exit the remote PowerShell session.

In this article, we will discuss how to use the exit keyword in PowerShell to exit the script.

We will discuss with examples other cmdlets which are used in the script as an Exit function like Exit, Break, Return and Exit-PSSession.

Let’s practice!

Using PowerShell Exit keyword

Exit keyword in PowerShell can terminate the script, console session.

If you open the PowerShell console and type exit, it will immediately close.

PS C:\> Exit

Using the Exit keyword in a script terminates only the script and not the console session from where we run the script.

Save the script in the file as FuncTest.ps1

Function ExitFunctionTest{
Write-Output "Inside function..."

The next step is to call the script from the console.

It will display the “Inside Function…” message on the console and stop PowerShell script.

The console will remain open as is.

Using Break Keyword

Break keyword is mainly used in loops in PowerShell like ( For, while, foreach, do-while, etc..).

It exits from the current loop.

for($count =1; $count -lt 5;$count++) {

	if($count -eq 3)
		{ break}
   Write-Output "Current Counter Value:" $count

In the above example, we have used for loop to demonstrate PowerShell exit functionality using the break keyword.

$count variable value increment by +1 on each iteration.

Inside the for loop, it checks for conditions if the value of $count is equal to 3, it executes the break statement.

This will terminate the for loop and exit for a loop.

It stops PowerShell script and starts executing the next statement after for loop.

The output of the above PowerShell exit script using break is:

Break inside a loop - PowerShell
Break inside a loop – PowerShell

Using Return Keyword

Using the Return keyword in the PowerShell script returns to the point where it invokes it.

Return keyword doesn’t terminate the script or session.

Let’s understand the return keyword with an example.

Function CheckStatus ($bitStatus){
	If($bitStatus = 2) 
			return $true
			return $false

	Write-Output "Bit Status check function called"  		

Write-Output "Call to Bit Status check function"
CheckStatus(2) # Invoke the function
Write-Output "CheckStatus function called"

In the above example of PowerShell exit script,

function CheckBitStatus returns the true if bitStatus is equal to 2.

You can return any type of value.

After evaluating the condition, it exit from the function returns to the point from where it was called and continues with further statement execution.
