Read from Linux named pipe - Mathematica

[Swamp Thing]

I have a named pipe :

mkfifo /home/pi/Desktop/gnuradio/PIPE

I can see the pipe in the Linux directory listing and also using Directory[] in Wolfram. I can test it in the console using echo and cat.

But Wolfram doesn't seem to see it:

In[10]:= FindFile["/home/pi/Desktop/gnuradio/PIPE"]
Out[10]= $Failed

OpenRead also gives "$Failed".

Is it possible to read from a Linux named pipe in Wolfram/Mathematica?

I do not know Mathematica much, but a pipe is not a regular file so it is perhaps not surprising if file functions in Mathematica filter out non-regular files. Searching the net it seems some have managed to use named pipes with Mathematica (e.g. https://stackoverflow.com/questions/6462275/mathematica-and-c-c-exchanging-data/6468874#6468874, 13 years ago though), but others fail and end up doing something else, like reading from a socket via a helper program.

You can use Duo Names to simplify managing Linux named pipes when integrating with Mathematica. For instance, setting up a persistent pipe and assigning descriptive names ensures smoother communication between processes.
