Random wallpaper with random fortune

Dependencies

• fortune
• imagemagick
• feh (you could easily do with something else here, replace line 35 in the script)

Usage

You just dump a bunch of .JPG or .PNG wallpapers you like in a folder and change the DIR variable in the script. Give it the path to the temporary directory that it should use and pick a fortune file. (you can see all files available by typing 'fortune -f' on the commandline) Then run the script and it will give you a new random wallpaper with a random fortune on it every 5 minutes. You can change the time between the different wallpapers by changing the TIMETOSLEEP variable.

The script

#!/bin/sh

#Configurables:
DIR=/home/USERNAME/Pictures/Wallpapers
TEMPDIR=/tmp
FORTUNEFILE=wisdom
TIMETOSLEEP="5m"

RANGE=$(ls -1 "$DIR"/*.jpg "$DIR"/*.png | wc | awk '// {print $1}')
FLOOR=1

number=0

overlayfortune()
{
   fortune -s $FORTUNEFILE | expand > $TEMPDIR/quote.txt
   width=$(identify -format %w "$1");
   convert -background '#0006' -fill white -gravity east -size ${width}x80
   caption:@$TEMPDIR/quote.txt
   "$1" +swap -gravity south -composite $TEMPDIR/background.png
}

while [ 1 -eq 1 ]; do

   number=$RANDOM
   while [ "$number" -le $FLOOR ]; do
      number=$RANDOM
   done
   let "number%=$RANGE" # Scales $number down within $RANGE.
   COUNTER=1
   for X in "$DIR"/*.jpg "$DIR"/*.png
   do
      if [ $number -eq $COUNTER ]; then
         overlayfortune $X
         feh --bg-scale $TEMPDIR/background.png
      fi
      COUNTER=$(($COUNTER+1))
   done
   COUNTER=1
   sleep $TIMETOSLEEP
done

Disclaimer

I don't think there's a lot that could go wrong here but don't blame me if you do screw up. It works fine here.
