"If you want the system to play an audio file whenever a new
file/directory is created in your home directory, use this
incrontab entry: /home/linuxlala IN_CREATE paplay
/usr/share/sounds/pop.wav. The command /home/linuxlala IN_CREATE rm
-rf $@/$# works similarly but its purpose is far more evil. With
this entry in the incrontab file, any directory or file created in
the user's home directory would be immediately deleted. The special
symbols, or wildcards ($@/$#), convey the complete path of the
newly created file to the rm -rf command."
