Guid converter

GUID (globally unique identifier) is a synonym for UUID (universally unique identifier). GUIDs are used by many applications as unique identifier for objects. In Oracle GUIDs ar represented using a RAW(16) datatype. Unfortunately, the byte order is different from the standard hyphen-separated GUIDs used in applications.

This small guid converter app, written in kotlin converts the standard hyphen-separated format into RAW(16) format and back. It is possible to convert single values to stout or values from input file to output file.

Using as standalone app

To use the guid converter as standalone app a cli control is implemented. If you call the app without subcommand/option, nothing will happen.
