While the switch statement is typically used to evaluate a single value, it can also be used to evaluate arrays. By using the -File parameter with the switch statement, it will treat each line of the file as an array item, allowing you to process a text file line-by-line and take actions when a specific value is found. You can use the typical switch parameters to match on exact text, wildcards, or regular expressions.
