Python and Notify OSD
Silly little bit of code that will tell you when a command line operation has finished.
#!/usr/bin/env python
import sys
import pynotify
if __name__ == '__main__':
if not pynotify.init ("icon-summary-body"):
sys.exit (1)
print sys.stdin.read()
n = pynotify.Notification ("Finished")
n.show()
This was based on https://wiki.ubuntu.com/NotificationDevelopmentGuidelines?action=AttachFile&do=view&target=icon-summary-body.py over on the article Notify OSD.
