Problem
You want to control the conditions under which PowerShell executes commands or portions of your script.
Solution
Use PowerShell’s if, elseif, and else conditional statements to control the flow of execution in your script.
For example:
$temperature = 90
if($temperature le 0)
{
"Balmy Canadian Summer" } elseif($temperature le 32) {
"Freezing" } elseif($temperature le 50) {
"Cold" } elseif($temperature le 70) {
"Warm" } else {
"Hot" }
Discussion
Conditional statements include the following:
if statement Executes the script block that follows it if its condition evaluates to true
elseif statement Executes the script block that follows it if its condition evaluates to true, and none of the conditions in the if or elseif statements before it evaluate to true
else statement Executes the script block that follows it if none of the conditions in the if or elseif statements before it evaluate to true
