PowerShell Alias – Documentation for Alias Definitions for PowerShell Arguments with Get-ChildItem

aliaspowershell

In an answer here on superuser.com, it is pointed out that gci -af is an alias for gci -File. That information is correct, and both command lines produce the same result of file listings.

However, I have not been able to find out a source of documentation where the -af alias is defined. For example, it is not defined in the primary documentation page for Get-ChildItem.

Is there another set of aliases for command line arguments when the command name itself is abbreviated, as in using gci for Get-ChildItem?

Down on the parameter lists of the documentation, you can find that -af is inded documented as an alias of -File.

-File

To get a list of files, use the File parameter. You can use the Recurse parameter with File.

The "duplicate name exists" error is because the (NetBIOS) name of the Windows computer conflicts with some other name on the network. The instructions tell you how to resolve the issue - Go to System in Control Panel to change the computer name and try again.

You need to change your computer's name since windows won't allow PCs to have the same name in the same workgroup.

You will need to reboot to flush everything out.

The Aliases is always a collection. Use

(Get-Command Get-ChildItem).Parameters.Values |
   Where-Object {$_.Aliases.Count -eq 0} |
      Select-Object Aliases, Name

Aliases Name
------- ----
{}      Path
{}      Filter
{}      Include
{}      Exclude
{}      Depth
