The if-statement is pretty important if you are creating PowerShell scripts. So I created this post to get some basic information about how to use if-else statements with PowerShell.
PowerShell if-else statement basics
Like many other languages, PowerShell has statements for conditionally executing code in your scripts. One of those statements is the If statement.
First, the syntax with a simple if:
if (condition) {do}You can also use elseif and else:
if (condition) {do}
elseif (condition) {do}
else {do}A simple if could look like this:
if ($varibale -eq "1") {
Write-Host "Yes variable is 1"
}
Comparison Operators:
- Equal to:
-eq - Less than:
-lt - Greater than:
-gt - Greater than or Equal to:
-ge - Less than or equal to:
-le - Not equal to:
-ne
You can also check case-sensitive by adding a “c” to the operator. “-eq” would be “-ceq“
Logical Operators:
- Not
-not - Not
! - And
-and - Or
-or
So you can simply add multiple conditions:
if ($varibale -eq "1" -or $varibale -eq "2") {
Write-Host "Varibale is 1 or 2"
}
Conclusion
I hope this provides you with a simple and short overview of how to use if-else statements with PowerShell. If you have any questions feel free to leave a comment. If you want to learn more, check out Microsoft Docs.
