Just a tool for a dynamic background with images from artsicle... Made for fun and training shell

art_grabber.sh

# Uses:
#       folder=/path/to/arts origin=artsicle_username WAIT_TIME=1 FORMAT=zoom ./art_grabber.sh
#       ./art_grabber.sh

folder=${folder:=/tmp/arts} # Folder for cache the images
origin=${origin:=regisdsm} # Your artsicle username
WAIT_TIME=${WAIT_TIME:=300} # Time between each wallpaper in seconds
FORMAT=${FORMAT:=spanned} # Possible values are "none", "wallpaper", "centered", "scaled", "stretched", "zoom", "spanned".


#Create and change folder
mkdir -p $folder
cd $folder

#Sets wallpaper format
gsettings set org.gnome.desktop.background picture-options $FORMAT
