Okay I think I found the answer. The $ isnt used for strings but for input parameter variables like argv[0..X] in c. There is a bug with bash $(0) as opposed to bash $0 when this is evaluated $(exansion) if that evaluates to $(0) it calls the bash command and send text as $1
Additionally, The Terminal Emulator disables bell I need to set the apropriate variables as discussed on http://docs.xfce.org/apps/terminal/start
I am trying to learn this I was told I need to be in audio permissions group and dsp is not supported in kernel. I am trying to prefix the pipe with the sudo command
cd /dev/snd && ls pcm* | shuf -n 1 &| (sudo &1 /dev/dsp)
What should &1 be set to $1 or $2? perhaps a form of sudo !! So that I can prefix sending the audio to dev/dsp
Or would I change to
cd /dev/snd && ls pcm* | shuf -n 1 &| sudo cat (data that Im Piping) /dev/dsp)
Let me clarify how do I reference the actual data in the &| command do I need the sed -e 's_^_man _' or is there another way to do this?
I am trying to use the old PC speaker not the sound card or alsa.
I may have similar issues to Why won't Linux let me play with /dev/dsp? I need to resolve to like I never learned how to give audio group permissions etc

The pipeline that you include has a couple of unusual tokens:&|and&1. Can you explain what these are supposed to do? Also, could you describe what the pipeline is aiming at doing as a whole? At the moment, it seems as if your are trying to pick a random file matchingpcm*under/dev/sndand do... something with it? How is yoursedcommand connected with this?

see man bash | grep "|" this line If |& is used, for 2>&1 |. This implicit redirection of the standard error to the operators ;, &, &&, or ||, and optionally terminated by one of ;, &, or Of these list operators, && and || have equal precedence, followed by ; the && and || control operators, respectively. AND and OR lists are command1 || command2

The pipeline that you include has a couple of unusual tokens:&|and&1. Can you explain what these are supposed to do? Also, could you describe what the pipeline is aiming at doing as a whole? At the moment, it seems as if your are trying to pick a random file matchingpcm*under/dev/sndand do... something with it? How is yoursedcommand connected with this?
