update darktable's thumbnail cache


    darktable-generate-cache [-h, --help; --version] [-m, --max-mip <0-7>] [--core <darktable options>]


darktable is a digital photography workflow application for Linux, Mac OS X and several other Unices. It's described further in darktable(1).

darktable-generate-cache updates darktable's thumbnail cache. You can start this program to generate all missing thumbnails in the background when your computer is idle.


All parameters are optional. If started without parameters darktable-generate-cache uses reasonable defaults.

-h,  --help

Gives usage information and terminates.


Gives copyright and version information and terminates.

--min-mip <0-7>
-m,  --max-mip <0-7>

darktable can handle and store thumbnails with up to eight different resolution steps for each image. These parameters define which maximum resolution should be generated and default to a range of 0-2. There is normally no need to generate all possible resolutions here; missing ones will be automatically generated by darktable the moment they are needed. When asked to generate multiple resolutions at once, the lower-resolution images are quickly downsampled from the highest-resolution image.

--min-imgid <N>
--max-imgid <N>

Specifies the range of internal image IDs from the database to work on. If no range is given, darktable-generate-cache will process all images from the entire collection.

--core <darktable options>

All command line parameters following --core are passed to the darktable core and handled as standard parameters. See darktable(1) for a detailed description of the options.
