androcontrol-notify

#!/bin/sh
# androcontrol-notify — desktop notifications for AndroControl connect/disconnect.
#
# The AndroControl server runs sandboxed as a dedicated system user and can't reach a
# graphical session, so notifications are delivered from the user's side: this script
# tails the service journal and pops a libnotify desktop notification on each
# connect/disconnect. Run it as a systemd --user service inside your graphical session.
#
# Requirements: systemd-journald, libnotify (notify-send), and a running notification
# daemon. Your user must be able to read the service journal (member of the
# systemd-journal / wheel / adm group).
#
# Install (any systemd distro):
#   install -Dm755 androcontrol-notify         ~/.local/bin/androcontrol-notify
#   install -Dm644 androcontrol-notify.service ~/.config/systemd/user/androcontrol-notify.service
#   systemctl --user daemon-reload
#   systemctl --user enable --now androcontrol-notify
#
# Env:
#   ANDROCONTROL_UNIT  systemd unit to watch (default: androcontrol)
