Re: [MSH]about cmdlet's hidden parameter's question

As /\/\o\/\/ pointed out get-command can show the actual parameters that are
taking affect. The provider cmdlets like get-childitem using the
IDynamicParameters interface to allow providers a way to extend the
parameters for the cmdlet. The help for each specific provider should
detail these parameters.

To expand on /\/\o\/\/'s example.

MSH C:\temp\monad\main> get-command get-childitem c: -usage
Get-ChildItem [[-Path] <String[]>] [[-Filter] <String>] [-Include
<String[]>] [
-Exclude <String[]>] [-Recurse] [-Force] [-Verbose] [-Debug] [-ErrorAction
<Act
ionPreference>] [-ErrorVariable <String>] [-OutVariable <String>]
[-OutBuffer <
Int32>]
Get-ChildItem [[-Path] <String[]>] [[-Filter] <String>] [-Include
<String[]>] [
-Exclude <String[]>] [-Recurse] [-Force] [-Name] [-Verbose] [-Debug]
[-ErrorAct
ion <ActionPreference>] [-ErrorVariable <String>] [-OutVariable <String>]
[-Out
Buffer <Int32>]


MSH C:\temp\monad\main> get-command get-childitem cert: -usage
Get-ChildItem [[-Path] <String[]>] [[-Filter] <String>] [-Include
<String[]>] [
-Exclude <String[]>] [-Recurse] [-Force] [-Verbose] [-Debug] [-ErrorAction
<Act
ionPreference>] [-ErrorVariable <String>] [-OutVariable <String>]
[-OutBuffer <
Int32>] [-CodeSigningCert]
Get-ChildItem [[-Path] <String[]>] [[-Filter] <String>] [-Include
<String[]>] [
-Exclude <String[]>] [-Recurse] [-Force] [-Name] [-Verbose] [-Debug]
[-ErrorAct
ion <ActionPreference>] [-ErrorVariable <String>] [-OutVariable <String>]
[-Out
Buffer <Int32>] [-CodeSigningCert]

Note, that the second call passes "cert:" as the path to the get-childitem
cmdlet and you now see -CodeSigningCert as a parameter where it wasn't
available in the FileSystem provider.

It depents on the provider the command does action :

the CodeSigningCert parameter is only shown in the second example (acting
agains the cert: store)


MSH>get-command get-childitem c: | select -expand parametersets | select
parameters | fl


Parameters : {Path, Filter, Include, Exclude, Recurse, Force, Verbose,
Debug, ErrorAction, ErrorVariable, OutVariable,
OutBuffer}

Parameters : {Path, Filter, Include, Exclude, Recurse, Force, Name,

Debug, ErrorAction, ErrorVariable, OutVari
able, OutBuffer}



MSH>get-command get-childitem cert: | select -expand parametersets |
select
parameters | fl


Parameters : {Path, Filter, Include, Exclude, Recurse, Force, Verbose,
Debug, ErrorAction, ErrorVariable, OutVariable,
OutBuffer, CodeSigningCert}

Hello,everyone here:
I have one problem and one suggestion.

##########
"get-help about_signing:"
I found:
dir cert:\CurrentUser\My -codesign
$cert = @(get-childitem cert:\CurrentUser\My -codesigning)[0]
##########
get-childitem have some hidden parameters?
Or "-codesign" didn't work anymore because the example is out of date?


##########

Using "get-help get-content",I can't find the "encoding" parameter.

Otherwise using the following method :
(get-command get-content).parametersets"
get-command get-content | select -expand parametersets
(get-command get-content).definition

So will the hidden parameters' usages be included in the next dropping
of
help files?
(I think implement it will helping people utilize the monad's power.)

Thanks for your comment.
