Thanks this works (if you add shell=True in Popen). If I don't want to use shell = True, how can I redirect the stdout to named_pipe? Popen accepts an open file handle for stdout, which I can't open for writing because that blocks the process...
You're back to using separate threads for the reader and the writer. The one that opens the pipe first will block until the other one opens the other end.
os.mkfifo("named_pipe", 0777) ls_process = subprocess.Popen("ls -lah > named_pipe") pipe = open("named_pipe", "r") # Read the output of the subprocess from the pipe. When the subprocess terminates (look at the docs for Popen objects), close and delete the fifo.
