Listing 1. Random Background Script

#!/usr/bin/perl -w
# This picks a random background from
# /usr/local/lib/X11/backgrounds,
# and calls an image viewer to set it as the
# background.
# This script is released under the GPL version 2.
# Putting the picture into a sub-directory named
# max will make sure it is
# resized to take up the whole background.
# Feel free to change the directory the images are
# stored in...
$bkgddir = "/usr/lib/X11/backgrounds";
# And if you'd like to use a different viewer, set
# it here.
