If statement is one of the most useful commands in PowerShell. You can execute code blocks based on the evaluation of the statement. Here is a simple example of an if statement. if(2 -eq 2){ Write-Host "2 is equal to 2." } If the specified condition in parentheses () evaluates to $true, then it runs the command in the braces {}. Output: 2 is equal to 2. If the condition is $false, it will skip that code block.
