### How to use this
|
|
#
|
|
## Set this script to run minutely as unprivileged user (not root)
|
|
# below path is an example and you may need to change it for it to work right
|
|
# This example assumes that you extracted the tarball or pulled the git repo to
|
|
# ~/Pictures/Wallpapers
|
|
# * * * * * $HOME/Pictures/Wallpapers/xkcd-clock/wallpaper_setter.sh
|
|
#
|
|
# You might have issues like stretched, squised or tiled image
|
|
# below commands may help solving those issues
|
|
# GNOME
|
|
# gsettings set org.gnome.desktop.background picture-options "scaled" 2> /dev/null
|
|
|
|
# locate where the images are
|
|
BG_REPO=$(dirname -- $(readlink -fn -- "$0"))
|
|
|
|
# Find out which image should be set as wallpaper
|
|
TimeZone='Pacific/Fiji' # I don't care where you are. Don't change this.
|
|
HOUR=$(TZ=$TimeZone date +%H) #; echo $HOUR
|
|
MINUTE=$(TZ=$TimeZone date +%M) #; echo $MINUTE
|
|
Remainder=$(( $MINUTE % 15 )) #; echo $Remainder
|
|
MINUTE=$(( $MINUTE - $Remainder )) #; echo $MINUTE
|
|
|
|
# If Minute is single digit at this point, add a zero before it to match file
|
|
# naming scheme
|
|
if [ $MINUTE -le 9 ];
|
|
then
|
|
MINUTE=`echo 0$MINUTE`
|
|
fi
|
|
|
|
# Finally generate new background's complete path
|
|
BG_PATH="$BG_REPO/$(echo $HOUR)h$(echo $MINUTE)m.png" #; echo $BG_PATH
|
|
|
|
# Set the new background
|
|
# GNOME
|
|
# There are 2 commands because GNOME can set different wallpapers for light
|
|
# and dark themes.
|
|
gsettings set org.gnome.desktop.background picture-uri "$BG_PATH" 2> /dev/null
|

gsettings set org.gnome.desktop.background picture-uri-dark "$BG_PATH" 2> /dev/null
