Hey everyone! I'm curious if there's a way to tell a built-in PowerShell command, like 'Get-Content' (or 'cat'), to accept arguments from the pipeline without overwriting the command itself. For example, when I do something like "filename.txt" | cat, I get an error saying that the input object can't be bound to any parameters because it doesn't take pipeline input. Is there a method to remap the command so it would recognize -Path from pipeline input, while still allowing standard usage of the command? I plan to add this to my $profile, so I want to ensure it doesn't disrupt the original usage. Thanks a lot!

From what I've gathered, 'Get-Content' does accept pipeline input, but it needs the property to be specifically labeled as 'Path'. A standard way to use this command while utilizing the pipeline would be: `Get-Item "somefile.txt" | Get-Content`. Alternatively, you can use aliases like `gi "somefile.txt" | gc` to make it more streamlined.
You could write a helper function that would take the incoming pipeline object, extract the necessary properties, and then call the actual command with those parameters. Make sure to reference the correct properties of the piped object instead of trying to bind it directly in the command.
Another approach could be to create a proxy command. This wraps around the original command and allows you to define how the parameters are passed, including handling the pipeline input more gracefully. It might be overkill for this situation, but something to think about!
