Be sure to check out my Scripting4Crypto initiative. It’s a fun way to get into using cryptocurrencies all while getting your PowerShell needs met.
I want to share a function I created to quickly find a cmdlet(s) within the PWPS_DAB module. I realize you can use the Get-Command cmdlet or the Commands window with PowerShell to do the same. However, for me, I am constantly trying to remember the name of a cmdlet(s) and using one of the other tools just takes to long. ( Again, for me. )
So, this function will offer a way to quickly get a list of cmdlets from the PWPS_DAB module by Verb, Noun, Name or a combination of Verb and Noun. At the time of this post, the PWPS_DAB module contained 498 cmdlets.
Function
The following is the function definition and the help information.
FUNCTION Get-PWCommands {
<#
.SYNOPSIS
Used to get ONLY commands contained in the PWPS_DAB module.
.DESCRIPTION
Returns ONLY commands related to the PWPS_DAB module.
.EXAMPLE
# Returns all commands delivered with the PWPS_DAB module.
Get-PWCommands -Verbose
# Returns all commands with the word userlist in the cmdlet name.
Get-PWCommands -Name 'userlist'
# Returns all commands with the word Get in the verb portion of the cmdlet name.
Get-PWCommands -Verb 'get'
# Returns all commands with the word group in the noun portion of the cmdlet name.
Get-PWCommands -Noun 'group'
# Returns all commands with the word update in the verb portion of the cmdlet name and user in the noun portion of the cmdlet name.
Get-PWCommands -Verb update -Noun user
#>
...
}
Parameters
There are three parameters available, Name, Noun, and Verb. None of then are required and one or more can be included.
[CmdletBinding()] param ( [ValidateNotNullOrEmpty()] [Parameter( Position = 0, HelpMessage = "Specifies the name of the PowerShell cmdlet to search for." )] [string] $Name, [ValidateNotNullOrEmpty()] [Parameter( HelpMessage = "Specifies the 'noun' within the PowerShell cmdlet name to search for." )] [string] $Noun, [ValidateNotNullOrEmpty()] [Parameter( HelpMessage = "Specifies the 'verb' within the PowerShell cmdlet name to search for." )] [string] $Verb ) # end
Code
The following shows the meat of the function. I have included the BEGIN, PROCESS, and END code blocks even though not all are used. This is to maintain my own formatting. Obviously, you can exclude those if you like.
You can see that I am taking advantage of the Get-Command cmdlet, however, I am limiting the scope to the PWPS_DAB module. Also, all parameter values are being wildcarded by default to eliminate the need to enter the wildcards within the provided parameter values. Simplifies the process.
BEGIN { <# Nothing to do here #>} # end BEGIN...
PROCESS {
$Splat_GetCommand = @{
Module = 'PWPS_DAB'
}
if( -not ([string]::IsNullOrEmpty($Name))) {
$Splat_GetCommand.Name = "*$Name*"
}
if( -not ([string]::IsNullOrEmpty($Noun))) {
$Splat_GetCommand.Noun = "*$Noun*"
}
if( -not ([string]::IsNullOrEmpty($Verb))) {
$Splat_GetCommand.Verb = "*$Verb*"
}
$ReturnValue = Get-Command @Splat_GetCommand | Select-Object Name
} # end PROCESS...
END {
Write-Output $ReturnValue
} # end END...
} # end FUNCTION Get-PWCommands...
Getting Commands
Now that you have the function, lets see what you can do with it.
Get ALL Commands
To return all commands, you simply call the function without including any parameters.
# Get all cmdlets in the PWPS_DAB Module. Get-PWCommands
The following shows a small portion of the results. Again, there are nearly 500 cmdlets, so listing them all would be foolish.
Get-Cmdlets By Name
When using the Name parameter, all cmdlets containing the provided value will be returned. This is regardless of whether the value is in the verb or noun. Also, this cmdlet is set to use the the positional value of zero. So, if you don’t specify a parameter and you pass a value, it will be assumed to use Name.
# Get cmdlets with the provided name in the PWPS_DAB Module. Get-PWCommands -Name set
The following shows a portion of the results.
Notice that the word set is included somewhere in all of the cmdlets. This includes both the verb and noun parts of the cmdlet names.
Get Cmdlets by Verb
Here we will get all cmdlets which use the verb ‘Update’.
# Get cmdlets with the provided verb in the PWPS_DAB Module. Get-PWCommands -Verb update
The following shows the results.
Notice all cmdlets contain the verb Update.
Get Cmdlets by Noun
Here we will get all cmdlets which use the noun environment.
# Get cmdlets with the provided noun in the PWPS_DAB Module. Get-PWCommands -Noun environment
The following shows the results.
Notice that there are different verbs being returned and all nouns contain the word environment.
Get Cmdlets by Verb and Noun
Finally, we will provide a verb and a noun combination to filter the results a bit more.
# Get cmdlets with the provided verb and noun combination in the PWPS_DAB Module. Get-PWCommands -Verb get -Noun document
The following shows all of the cmdlets containing the verb get and the noun document.
Notice, every cmdlet has the verb Get and every noun contains the word Document.
Summary
Again, the reason for this function is to expedite the process of getting cmdlet names available in the PWPS_DAB module. By providing one or more of the parameters, the returned list of cmdlet names will be filtered down. For me it is much quicker than using the Command window or the Get-Command cmdlet.
Experiment with it and have fun. And please, let me know if there is a topic you would like to see a post for. Or share a solution you have developed.
