This method of piping commands is independent of EG, and will start it up if not already running. This is very useful if I need to restart it remotely. Events are sent to Eventghost through subscribing to topic "ghost" on my MQTT broker.

# This method of piping commands is independent of EG, and will start it up if not running,

# Events are sent to Eventghost through subscribing to topic "ghost" on my MQTT broker

# First, I use Windows task scheduler to run WSL on Windows boot.
# > cat bootpm2onwsl.bat
# sleep 5
# wsl pm2 start "sh ~/bin/mqtt_eg_link.sh" --watch &

# Since WSL has no init, This is not 100% reliable, 
# so I have added a redundent call to "pm2 resurrect" in my .bashrc
# This is not the best method to init, but so far the added resurrect has had no ill effects

# Add the below function to your .bashrc in order to fix the interop socket.
# Be sure to replace the broker and port with your own.
