Where can I find documentation for notify-osd?

Question

Whenever something happen which require notification (connecting to a wireless network or low battery status) Ubuntu (unity) gives a nice floating message which (usually) vanishes after several seconds. Is there a way to produce my own floating notification?

Answer 1

notify-send "whatever you want to say :)"

You can put it in your scripts to notify you about almost anything happens in your system. To see more options like setting title, icons, time, etc...

man notify-send

Answer 2

Have you checked out the ubuntu wiki yet?

There's a few examples here https://wiki.ubuntu.com/NotificationDevelopmentGuidelines

More general info about it here https://wiki.ubuntu.com/NotifyOSD

Answer 3

Caveat! If using the Unity desktop man notify-send is contradicted by Non-expiring notifications

For details see reference: http://askubuntu.com/a/189173/89468

The use of notify-send is desktop conditioned, depending on whether it is:

1. Unity's notify-OSD or
2. Gnome's notification-daemon

that displays the notification.

Quoting mhall119/devportal/notify-osd - Ubuntu Wiki:

notify-osd

... takes the place of notification-daemon, and its presentation of notification bubbles differs in several ways ...
