Hello,

In this article, I review the differences between Break, Return and Exit in Powershell, to help you choose the right statement. I don’t go into detail about the possibilities offered by these instructions, perhaps in a future article.

# Break
# Break allows you to exit While, Do, For, ForEach, Foreach-Object or Switch loops.
# Code creates an infinite while loop, break exits the loop
function Test-Break {

    while ($true) {
        "start while loop
        break # exits the loop
        "end while loop" # code not executed
        }
    "Code outside while loop"
}
Test-Break
"Next code"

# Return
# Return exits the active scope (function, script or script block)
function Test-Return {

    while ($true) {

        "Start while loop" # Return
         Return # Exits the function
        "End while loop" # code not executed
        }
}
Test-Return
"Next code"

# Exit
# Exit allows you to exit a script or a Powershell instance
function Test-Exit {

    while ($true) {

        "Start while loop" # Exit
         exit # Closes the Powershell instance

         "end while loop" # code not executed
        }
}
Test-Exit
"Next code" # code not executed
