Some command returns the value but not the Boolean value but they support parameter which returns the Boolean value. This command directly returns the Boolean value based on the path existence. Using those cmdlets which returns the output Boolean type. Example #1: Using Comparison Operators to check Boolean values. Let us discuss examples of PowerShell Boolean. It checks whether the last command run was successful or failed and it gives the output accordingly. Test-Connection -Count 2 -Quietĭollar + QuestionMark syntax ( $?) also produces the Boolean output. While Test-Connection, by default doesn’t produce the Boolean output but when we add -Quiet parameter, it produces the Boolean output. In the above example, if the condition checks whether the expression is true or false and that is a Boolean value and based on it, the script executes the block.įew commands also directly return the Boolean values like Test-Path, Test-Connection, etc. If the condition is true then it uses the ‘IF’ block, otherwise else block is executed. In the first example, 2 is automatically type-casted to Boolean while in the second example, $true is type-casted to the integer as shown below.Ĭondition like IF/Else also uses the Boolean output.
PowerShell allows you to work with different data types such as strings, integers, floats, arrays, etc., and convert variables to strings, especially when displaying the output to the user. It works on the typecasting and the left side of the object type plays the main role here. In PowerShell, you can convert the variable to a string using the ToString() method or the -f format operator. Return Boolean from Function in PowerShell Get Filename without. So when the first example is true, its reverse should be also true but the Boolean operator doesn’t work that way. Use Convert::ToInt32() method to convert the specified string to int in PowerShell. In the above example, the first is true but the second is false. In the above examples we have seen that the left side of the object is compared to the right side of the object in the -EQ operator but let evaluate the below expressions. In the Boolean type, 1 is treated as $true, and 0 is treated as $false. If we use the case-sensitive operator then the output will be false. For example, the above operator is not case sensitive.
