Itâ€™s always a good idea to include help within your functions ! You never know who might benefit from it.
With PowerShell adding help to your script, function and module is a really easy thing to do.
Help in the PARAM statements
A very cool way to add some help to your script parameters is to add comments within the PARAM statement block. With this method you do not need to write a .PARAMETER directive for each paremeters. However you are required to write at least one directive in the Comment Based Help block (.SYNOPSIS or .DESCRIPTION) to be able to use it.
<# .SYNOPSIS This function will get some cool stuff #> PARAM( # Specifies the computer name $ComputerName, # Specifies the Log directory Path $Logs = C:\lazywinadmin\logs )#PARAM
Then use Get-Help against your function/script
Get-Help Get-Something -Parameter *
This command will only return the Parameters information with the help we added in the PARAM statement
-ComputerName <string> Specifies the ComputerName Required? true Position? named Default value Accept pipeline input? false Accept wildcard characters? false -Logs <string> Specifies the Log directory Path Required? false Position? named Default value c:\lazywinadmin\logs Accept pipeline input? false Accept wildcard characters? false </string></string>
Even if this tip is pretty cool, I would still recommend to use the Comment Based Help block to have a centralized place to put all the help !
