BEST PRACTICES

2014

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 Help command’s –online parameter is used.

2014

Find custom commands this way

Refresh the command list

Actions you can take once you fill in parameters
