Output filename when output to file unless set to silent.

Is this block of code where you're talking about implementing verbose filename output logging?

rbedit/cmd/common/metadata.go

Lines 192 to 226 in 07d4377

	switch outputType {
	case fileOutputTypeName:
	if len(outputValue) == 0 {
	return nil, fmt.Errorf("missing valid output destination")
	}
	return outputs.NewSingleOutput(opts.defaultEncodeFn, outputs.NewFileOutput(outputValue)), nil
	case fileOutputWithInplaceTypeName:
	return outputs.NewSingleOutput(opts.defaultEncodeFn, outputs.NewInplaceFileOutput()), nil
	case fileOutputWithTemplateFilenameTypeName:
	if len(outputValue) == 0 {
	return nil, fmt.Errorf("missing valid output destination")
	}
	return outputs.NewSingleOutput(opts.defaultEncodeFn, outputs.NewFileOutputWithTemplateFilename(outputValue)), nil
	case printTemplateTypeName:
	if len(encodeValue) == 0 {
	return nil, fmt.Errorf("missing valid print template")

	return outputs.NewSingleOutput(encodings.NewEncodePrintTemplate(encodeValue), outputs.NewStandardOutput()), nil

	default:
	return nil, fmt.Errorf("unknown output destination type: %s", outputType)
	}

A while ago since I wrote it, but does look reasonable.

I'm using this and thought that this would also be useful, so once I saw an issue on it, I figured I'd just submit a PR if it still needed to be done. I'll should have some time in the next few days to look at it.
