In PowerShell, you may encounter the error “The term is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.”
Let’s look at how to fix this.
In the example below, I have a function called Add2, which adds 2 numbers:
The code:
$num1 = 5
$num2 = 10
Add2 $num1 $num2
function Add2($num1, $num2) {
$num3 = [int]$num1 + [int]$num2
Write-Output $num3
}
The problem here is PowerShell is not aware of the function at the time of running. If you were to run this a second time, you probably won’t encounter the error as the function is now declared after the first iteration.
Changing the order of this, where the function is written first:
function Add3($num1, $num2) {
$num3 = [int]$num1 + [int]$num2
Write-Output $num3
}
$num1 = 5
$num2 = 10
Add3 $num1 $num2
Now when running this, we do not get the error:
