14 The xscreensaver-getimage-file program is a helper program for the
15 xscreensaver hacks that manipulate images. Specifically, it is invoked
16 by xscreensaver-getimage(1) as needed. This is not a user-level com‐
17 mand.
18
19 This program selects a random image from disk, and loads it on the root
20 window. It does this by figuring out which image-loading programs are
21 installed on the system, and invoking the first one it finds.
22
24 xscreensaver-getimage-file accepts the following options:
25
26 --verbose
27 Print diagnostics.
28
29 --name
30 Don't load an image: instead just print the file name to stdout.
31
32 directory-or-URL
33 If a directory is specified, it will be searched recursively for
34 images. Any images found will eligible for display. For effi‐
35 ciency, the contents of the directory are cached for a few hours
36 before it is re-scanned.
37
38 If a URL is specified, it should be the URL of an RSS or Atom feed
39 containing images. The first time it is accessed, all of the
40 images in the feed will be downloaded to a local cache directory.
41 If a few hours have elapsed since last time, the URL will be polled
42 again, and any new images will be cached, any images no longer in
43 the feed will be expired.
44
45 --no-cache
46 Update the cache immediately, even if it is not time yet. This
47 will re-scan the directory, or re-poll the RSS feed.
