Continuing my series on PowerShell basics, in this installment we’ll talk bout looping in PowerShell. Looping is a mechanism for repeating a set of instructions multiple times, ending once a condition is met. Looping is also known as iterating, as in “iterating over an array”.
Loops continue until one of two things happen. In one type of loop, the loop continues until a certain condition is true. In the second type, the loop will iterate over a collection (also called an array) of objects until the entire collection has been gone through.
Read on for an enumeration of the different types of loops you can create with this language.
