NAME
xscreensaver-getimage-file - put a randomly-selected image on the root
window
SYNOPSIS
xscreensaver-getimage-file [-display host:display.screen] [--verbose]
[--name] [--no-cache] directory-or-URL
DESCRIPTION
The xscreensaver-getimage-file program is a helper program for the
xscreensaver hacks that manipulate images. Specifically, it is invoked
by xscreensaver-getimage(1) as needed. This is not a user-level com-
mand.
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.
OPTIONS
xscreensaver-getimage-file accepts the following options:
--verbose
Print diagnostics.
--name
Don't load an image: instead just print the file name to stdout.
directory-or-URL
If a directory is specified, it will be searched recursively for
images. Any images found will eligible for display. For effi-
ciency, the contents of the directory are cached for a few hours
before it is re-scanned.
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 im-
ages 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.
--no-cache
Update the cache immediately, even if it is not time yet. This
will re-scan the directory, or re-poll the RSS feed.
