xscreensaver-getimage-file(1)


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
   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.

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
       efficiency, 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
       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.

   --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.
