newbg - Set wallpaper like no-one's business
newbg [-d|-D subdir] [-v] [-n] [--list] [keywords...] echo 'root: /home/user/wallpapers' >> ~/.newbg newbg # random wallpaper newbg -d animals # random wallpaper from animals subdir newbg dinosaur # random wallpaper with dinosaur in filename # Adjust brightness newbg --darken [10] | --lighten [10] # View current wallpaper or history newbg [--current | --history] # Restore previous wallpaper on startup newbg -r
newbg is a simple utility to set the desktop wallpaper. Given a directory of wallpaper images, it will pick a random image subject to the subdirectory or filename restrictions you provide, and set it as background. It keeps track of previously set images and will cycle through them to avoid duplicates.
newbg
newbg keeps track of how long a wallpaper has been active and will be less likely to suggest wallpapers you change after a short amount of time.
Additionally, newbg can normalise the brightness of wallpapers and output a history of previously set images.
Pick wallpapers in which the filename contains at least one of the keywords provided. Case-insensitive.
-d
--dir
Specify the directory in which to look for a wallpaper. This directory is assumed to be a sub-directory of the root directory (see above), unless it begins with a slash ('/').
-D
As -d, except assume the directory is relative to the current working directory if it does not begin with a slash.
-r
--restore
Restore previously set wallpaper, without counting statistics. This is intended for use at startup.
--darken[=adjustment]
Darken the current wallpaper. The default adjustment is 10, but can be set. Your adjustment will be saved and applied when the wallpaper is picked again.
--brighten[=adjustment]
Brighten the current wallpaper (as above).
-n
--no-stats
Usually newbg will remember if you immedately switch to another wallpaper (by re-running the command) or seem to be happy with a wallpaper (but not re-running for a while) and factor this into future selections. This option disables this behaviour for the current invocation.
-l
--list
List wallpapers that could be picked, but don't set any.
--history
Show current and previously set wallpapers, with time since they were set.
--current
Print path of current wallpaper.
-v
--verbose
Output the filename of the selected wallpaper, and some other information.
--config
Override path to the newbg config file.
newbg's configuration is by default stored in $HOME/.newbg in YAML format. You can override this via either the --config option or the NEWBG_CONFIG environment variable.
$HOME/.newbg
NEWBG_CONFIG
The config file is used to store data about previous wallpaper selections and user preferences e.g. brightness adjustments. The following top-level keys may be set:
Path to the root directory of the user's wallpapers. Required.
Target average intensity of pixels in the wallpaper, as a floating point number [0,1]. If this config is set, images will have their brightness adjusted such that the average intensity becomes this value.
Holds configuration for each wallpaper, by SHA-1 hash of its contents. Relevant keys are 'good' (number of good votes), 'bad' (number of bad votes) and 'bright_adjust' (user-specified brightness adjustment for image).
