I'm using AntiX Linux, which is not using systemd, and I want to create a daemon in which I can echo to do something. How do I do that properly?
This is how I want to use it:
...
echo "got signal 1 use lock" > mydaemon
...

1If not using systemd, it is using sysv init scripts. Google it. You may also want to take a look at `supervisord`. – GMaster Apr 04 '20 at 14:40

2@GMaster: `If not using systemd, it is using sysv init scripts` - or busybox. Or runit. Or OpenRC. – Arkadiusz Drabczyk Apr 04 '20 at 14:43

The init system and how to configure your program to be run by it is just one part of the problem. You will have to write the program itself to become a daemon when run. This involves forking into the background, creating a new session and disassociating from the controlling terminal, among other things. These steps are not necessary with systemd, because systemd runs your program in a wrapper that performs all these steps for you, but other init systems typically don't.
