Best Practices


Use Functions• Function global:Do-Something(){• }

• Function global:Do-Something($someParameter){• }

• Function global:Do-Something{• param ([type]$someParameter=$(“Default Expression”))

• }


Follow the Naming Convention!

•Verb-Noun• 98 Verbs


Comment your functions• <#• .SYNOPSIS –a brief explanation of what the script or function does.

• .DESCRIPTION – a more detailed explanation of what the script or function does.

• .PARAMETER name – an explanation of a specific parameter. Replace name with the parameter name. You can have one of these sections for each parameter the script or function uses.

• .EXAMPLE – an example of how to use the script or function. You can have multiple .EXAMPLE sections if you want to provide more than one example.

• .NOTES – any miscellaneous notes on using the script or function.

• .LINK – a cross-reference to another help topic; you can have more than one of these. If you include a URL beginning with http:// or https://, the shell will open that URL when the Helpcommand’s –online parameter is used.
