mypipe | MySQL binary log consumer with the ability to act | Pub Sub library

bluetoothctl is an application that has a shell and accepts input commands. I would like to send command to it from the shell of the linux arbitrarily and I would also like to read its output without colours. I am on debian based linux (Raspbian buster) and would like to do it from bash shell if possible.

What I have tried so far:

Method one (sending commands via fd)

• Run the process attached: $ bluetoothctl
• Then from another terminal: $ echo "my command" > /proc/$(pidof bluetoothctl)/fd/0 and $ echo -e "my command\n" > /proc/$(pidof bluetoothctl)/fd/0 and $ echo -e "my command\013" > /proc/$(pidof bluetoothctl)/fd/0 but my command just appears as an output of bluetoothctl and even pressing 'enter' key on my keyboard in the terminal of the program does not execute the command at all just gives a new line.

Method two (writing output to a text file)

• Run the process detached: $ bluetoothctl > my.output &, but it exits from the application immediately

Method three (sending command via pipe)

• Create a pipe mkfifo mypipe
• Redirect the pipe to bluetoothctl cat mypipe | bluetoothctl > my.output
• Write a command to the pipe echo "my command" > mypipe, but it closes the application immediately and the application has no time to process the command asynchronously. Hence, does not work.

I believe the feasible solution would be to start the application detached $ bluetoothctl & and then send command to it via /proc/$(pidof bluetoothctl)/fd/0 and read its stdout and stderr via /proc/$(pidof bluetoothctl)/fd/1 and /proc/$(pidof bluetoothctl)/fd/2 but I am totally lost.

One of the command I would like to execute and read it's output is 'scan on' and ideally one bluetoothctl instance would process multiple commands not only one that the pipe can do. Can someone please advise how a command can be sent via fd, and how the output can be read via the another fd of the process. All of this in bash shell, if possible.

How can we customize the date from moment js? I want to display only Ex: Thu 10 of the month. How can we achieve that using moment or pipe need your help.

So I am doing the protostar challenges from exploit exercises and I'm completely stumped. Protostar runs on a virtual machine emulating an i686 processor.

how to pass pipes as parameter , I mean something like this :

I'm running Jenkins in a Docker container. Following this article, I'm bind mounting the Docker socket in order to interact with it from the dockerized Jenkins. I'm also bind mounting the container directory jenkins_home. Here is a quick recap on my volumes:

If you don't need to set global variables, or are willing to use named pipes, you can use:

In C# I am using BinaryWriter like this:

My program it's pretty big, so I'll highlight the main problem and add some details about it.

First part of my code:

this is my first approach to WCF and named pipes.

What I have to do is a windows service listening on a named pipe while a small GUI tells it what to do through the pipe.

Everything works well: calls are made to the service, responses are delivered to the GUI and the job gets done. But if I send two concurrent requests from the GUI then the service will process them one by one: I would like to manually manage concurrency service-side and let it run both requests at the same time.

I've tried creating 2 different pipes for the 2 requests and it does what I need, but of course it's not a solution.

I'm using .NET Framework 4.0 and I can't change it.

Here's my example code:
