Thank you! I knew that the systemd guys had all the basic pieces
together already. Now they only need to write the final pieces of the
new /usr/bin/wall-for-the-desktop-generation tool. I wrote my own in the
Fish shell:
#!/usr/bin/fish
set notify_program /usr/bin/fyi
set notify_args $argv
for session in (loginctl list-sessions --no-legend | cut -d' ' -f1)
set -l type (loginctl show-session $session -p Type --value)
if string match -qr '^(wayland|X11)$' $type
set -l user (loginctl show-session $session -p Name --value)
systemd-run --user -M $user@ -- $notify_program $notify_args
end
end
(Fish shell does not have sh-like word splitting so similar quoting is
not needed.)
