Feature Request / Get-Command <a cmdlet alias> should return the full info.

Summary of the new feature/enhancement

Get-Command <a cmdlet alias> should return the same info as to Get-Command <cmdlet full name>.

But currently, Get-Command <a cmdlet alias> only returns the cmdlet full name.

Demo on Invoke-WebRequest and its alias iwr

# Get-Command without any params

6.2.2> gcm iwr

Invoke-WebRequest

6.2.2> gcm Invoke-WebRequest -Syntax

Invoke-WebRequest [-Uri] <uri> [-UseBasicParsing] [-WebSession <WebRequestSession>] [-SessionVariable <string>] [-AllowUnencryptedAuthentication] [-Authentication <WebAuthenticationType>] [-Credential <pscredential>] [-UseDefaultCredentials] [-CertificateThumbprint <string>] [-Certificate <X509Certificate>] [-SkipCertificateCheck] [-SslProtocol <WebSslProtocol>] [-Token <securestring>] [-UserAgent <string>] [-DisableKeepAlive] [-TimeoutSec <int>] [-Headers <IDictionary>] [-MaximumRedirection <int>] [-MaximumRetryCount <int>] [-RetryIntervalSec <int>] [-Method <WebRequestMethod>] [-Proxy <uri>] [-ProxyCredential <pscredential>] [-ProxyUseDefaultCredentials] [-Body <Object>] [-Form <IDictionary>] [-ContentType <string>] [-TransferEncoding <string>] [-InFile <string>] [-OutFile <string>] [-PassThru] [-Resume] [-PreserveAuthorizationOnRedirect] [-SkipHeaderValidation] [<CommonParameters>]

Proposed technical implementation details (optional)

We expect to see exactly the same info between Get-Command iwr and Get-Command Invoke-WebRequest. And the same for all the params.

One important use of Get-Command is to find out what kind of command you have. Hiding the fact that your command is an alias by default is highly undesirable. However, I think it’s reasonable for Get-Command -Syntax to “follow the link” and give you the syntax of the aliased command. If this is done, I don’t see a particular need for a -Resolve parameter.

Good points, @copdips and @kilasuit - adding a -Resolve switch has been proposed before, in #7387
