Theoretically, producing fakes like the one above and wrongly
attributing them to others is a felony. Certainly in Germany and
probably in the country which has to endure your presence as well.

SUSv4/POSIX.1-2008 XCU section 2.7 Redirection:

Open files are represented by decimal numbers starting with zero.

implementations shall support at least 0 to 9, inclusive, for use
by the application. These numbers are called "file descriptors".
