I re-jigged the first script to make it more suitable for baseball.

Here is a classic example for dissecting, fiddling, changing stuff to see what happens, and thus truly learning how functions are constructed. Example 1: A PowerShell Function to Calculate Baseball Averages The whole point is that you can execute this block of PowerShell code simply by typing the name of the function. What you place inside the script block is the same code that you could execute normally outside the scope of the function. PowerShell dictates a format consisting of three parts, the keyword ‘Function’, followed by a name of your choice, finally, the payload containing the script block, which is enclosed by curly, or parenthesis style brackets. Casting aside sporting loyalties, these two scripts will get you started with PowerShell’s functions.īy using keyboard input, we are going to take two numbers and divide the first number by the second, and thus calculate the average in traditional math fashion.īefore we get down to using my Get-BatAvg Function, here are a few considerations.

Intermediates state – Functions are a method of saving time when tackling repetitive tasks.

Beginners say – Functions are mysterious even mythical.To elaborate on what I mean, let us consider three statements from people with different scripting knowledge: Are they a tool to be used occasionally for recurring blocks of code? Alternatively, will functions become the central methodology for every script we create? Firstly, let us think about our approach to PowerShell’s functions.
