Hi Phil,

I’ve been looking for something that describes command line options for the
various RD programs , especially RDAirPlay, but have had limited success. Is
there someplace I can look to find these options for RDAirPlay and others?
Thanks

The source code is the definitive place to discern command line options.
You can also try "man <COMMAND-NAME>" to see if there's a manual page
for the command (spoiler, there isn't one for rdairplay).
For those who haven't navigated the source code, here's a brief
introduction. Rivendell is primarily written in the language C++. Most
of the stand-alone apps are in their own subdirectory of the top-level
source code "tree" (e.g., "rdairplay/"). The "main" subroutine (its name
is actually "main" and it is the one in which command line options are
handled) is in a file with a base name the same as the subdirectory
(e.g., "rdairplay/rdairplay.cpp"; "cpp" is the extension for C++ source
code files).
When you view the file (using your favorite text file viewer or editor,
or just browsing it on GitHub
[https://github.com/ElvishArtisan/rivendell/blob/master/rdairplay/rdairplay.cpp]),
look for "RDCmdSwitch", this is the C++ object that is used to interpret
and act on command line switches. After locating that string in the
file, scroll down to see all the switches and the code that deals with them.
RDAirPlay and most of the other GUI Rivendell apps accept no command
line switches. RDLogManager is one of the notable exceptions. The
CLI-only commands (like RDImport) are located in the utils/
subdirectory. RDImport is a good example of a command that has a ton of
command line switches and also has a thorough manual page explaining all
of them).
Hope this helps!
