4. PowerShell Aliases

• The purpose of setting up the alias for PowerShell is to provide the new user with a shell that can interact quickly. The alias here refers to the alternate name of the cmdlet. For example: "Get-childitem" = "dir"

• Powshell built-in aliases list:
  Command: Get-alias
  For example? = Where-object; ls= dir
