PowerShell: If Else ElseIf Statements Examples

Let's take a look at how to perform if-else and if-elseif-else statements to perform conditional logic.

Example 1: If-Else Statement

Syntax:

if (condition) {
    # code to execute if the condition is true
} else {
    # code to execute if the condition is false
}

$age = 25

if ($age % 2 -eq 0) {
    Write-Host "Your age is even."
} else {
    Write-Host "Your age is odd."
}

Example 2: If-ElseIf-Else Statement

if (condition1) {
    # code to execute if condition1 is true
} elseif (condition2) {
    # code to execute if condition1 is false and condition2 is true
} else {
    # code to execute if both condition1 and condition2 are false
}

$num = 3

if ($num -eq 0) {
    Write-Host "The number is zero."
} elseif ($num -gt 0) {
    Write-Host "The number is positive."
} else {
    Write-Host "The number is negative."
}
