How to send a notification to another user with notify-send

Bash can write to network sockets but can't listen/read. You could use GNU Netcat for this functionality.

A network notify-reader listening on port 10000 (no security):

#!/bin/bash

# no multiple connections: needs to improve
while true; do
    line="$(netcat -l -p 10000)"
    notify-send -- "Received Message" "$line"
done

And a corresponding client:

#!/bin/bash

host="$1"
echo "$@" >/dev/tcp/$host/10000

So you can send messages using

notify-sender.sh  your-host message
