Use Splatting, Proxy, and Metadata in Powershell

Use Splatting, Proxy, and Metadata in Powershell

• Splatting is the ability to use a dictionary or a list to supply parameters to a command.
  
  Example:
  $MailMessage = @{
      To = “me@mycompany.com”
      From = “me@mycompany.com”
      Subject = “Hi”
      Body = “Hello”
      Smtpserver = “smtphost”
      ErrorAction = “SilentlyContinue”
  }
  Send-MailMessage @MailMessage
• Proxy commands are wrappers of existing commands in Windows PowerShell, and to make this possible, a number of different things had to be enabled in the language that can have interesting other uses.
• Metadata provides information about the command and parameters of different commands, and provides a structure that you can use to “write” a command without typing out the whole script.
