xscreensaver-getimage-file - put a randomly-selected image on the root window
program is a helper program
for the xscreensaver hacks that manipulate images. Specifically, it
is invoked by
as needed. This is not a user-level command.
This program selects a random image from disk, and loads it on the root
window. It does this by figuring out which image-loading programs are
installed on the system, and invoking the first one it finds.
accepts the following options:
Don't load an image: instead just print the file name to stdout.
If a directory is specified, it will be searched recursively for
images. Any images found will eligible for display. For efficiency,
the contents of the directory are cached for a few hours before it
If a URL is specified, it should be the URL of an RSS or Atom feed
containing images. The first time it is accessed, all of the images
in the feed will be downloaded to a local cache directory. If a few
hours have elapsed since last time, the URL will be polled again, and
any new images will be cached, any images no longer in the feed
will be expired.
Update the cache immediately, even if it is not time yet. This
will re-scan the directory, or re-poll the RSS feed.
