If / Then / Else Statements

In PowerShell, an if statement allows you to execute a block of code based on the evaluation of a conditional expression. An elseif clause allows you to specify additional conditions that are checked only if the previous if or elseif condition was false. An else clause specifies a block of code that is executed if all the previous conditions were false.

$x = 10

if ($x -gt 15) {

    # This block of code is executed if $x is greater than 15

    Write-Host "x is greater than 15"

} elseif ($x -lt 5) {

    # This block of code is executed if $x is less than 5

    Write-Host "x is less than 5"

} else {

    # This block of code is executed if none of the previous conditions are true

    Write-Host "x is between 5 and 15"

}
