If condition is one type of conditional operator. The if operator has a statement or value that needs to be evaluated and based on the result and the corresponding action is executed.

The if statement generally has one or multiple else statements followed by it. If the evaluation of condition is true, the code inside if block is executed else the code in the else part is executed. In case of If-Not it is nothing but negating the If block. This means if the condition is not met then if part is executed and if the condition if is met else part if is executed. This is also known as reversal of if operator.

Here we will see various if conditional operator and If-Not operator. The -Not operator is used to change an expression result from false to true or true to false.

The alias of -not is!. Note 5: Remember that with -Contains, and by extension -NotContains, the match has to be exact. Thankfully the utilities are displayed logically: monitoring, network discovery, diagnostic, and Cisco tools.

When you seek an exact value, then -Contains would be my first choice of conditional operator. Please email me if you have a better example script. Also please report any factual mistakes, grammatical errors or broken links, I will be happy to correct the fault. Challenge: Substitute -Match for -Contains. About The Author Guy Thomas.
