NAME
wallch - Wallpaper Changer
SYNOPSIS
wallch [options]
DECRIPTION
Wallch is a free and open-source application for managing your desktop background. It comes with
various functions, such as rotating your hard drive's wallpapers, live earth, wikipedia picture of the
day, wallpaper clocks and live website. It supports Gnome (with or without Unity integration), LXDE and
XFCE desktop environments. Wallch can work with or without its Graphical User Interface, for extra
lightweightness.
OPTIONS
Please notice that all the options, except from --change, --help, --cache, --fcache, and --version, will
be sent to the already running instance of Wallch, if there is one.
--help
Shows a menu with the available options.
--change[=DIRECTORY]
Picks a random image and sets it as desktop background from the last used folder. However, if a
DIRECTORY is specified, then that directory is recursively searched for images and a random one is
picked from there.
--start
Starts the wallpaper changing process using the last specified folder.
--earth
Starts the live earth process.
--potd
Starts the picture of the day process.
--clock
Starts the wallpaper clocks process.
--website
Starts the live website process.
--stop
Stops any running process, like live earth or picture of the day.
--quit
Closes any instances of the program.
--next
Proceeds to the next image, if available. This works only when the normal wallpaper changing process
is running.
--previous
Proceeds to the previous image, if available. This works only when the normal wallpaper changing
process is running.
--pause
Pauses the normal wallpaper changing process.
--cache DIRECTORY
Searches DIRECTORY recursively for supported images and caches them. This allows a much better
experience when viewing the images of this DIRECTORY from Wallch, because they load much faster.
Please note that this argument takes into consideration the cache limit and may delete some cached
images of the specified folder if this limit is exceeded. Wallch by default caches the images while
they are being viewed, so this option may only be used if the user does not want to wait for the
pictures to load and be cached when viewed for the first time from Wallch.
--fcache DIRECTORY
Same as --cache but without taking into consideration the cache limits. If you open Wallch's
Graphical User Interface afterwards, the limits will be taken into consideration and the extra
images will be deleted. Wallch calculates which images are most likely not to be seen according to
the last used folder, and it deletes the extra images from the cache, if the limit is exceeded. This
option is useful when you simply want to generate thumbnails for all the images in a folder or you
simply don't want to wait for Wallch to calculate and delete the extra images for the time being.
--version
Shows the program's version.
