Write your first basic barebone function in PowerShell.

Hey There, you can watch the live coding here on youtube. [embed]https://youtu.be/U0qd9um3ws4[/embed] Let us learn to write our first Powershell function. This is going to be a basic barebone function, this does not do much, just prints a string. We use function keyword to start definition of a function. Then we use start and end curly braces to define start and end of function code block. A very basic, bare bone function looks like this.

function Say-Hello {
    Write-Output "Hello";
}

The function keyword tells the powershell that we are starting a definition of a function.
Say-Hello word provides the name of the function
"Hello" is just a string literal
Write-Output function prints the string "Hello" to the terminal.

To run the function, just write the name and hit enter. Like shown in the screen shot, It is a screenshot of window command line, where Powershell Function is defined and executed, and function output is displayed.

You can see in the screenshot, I have defined a function in the first line. In the second line, I am calling that function. Which results in the function output Hello. Try running the code yourself for better understanding. You can learn to pass parameters in a function - on here.. Thank you - Anurag Anand
