I also look at my own backgrounds. I have some 23.000+ pictures and twi
screens. I used to have a randomizer, but that one did not really work
well, because it was not really random.
The script I use on my WindowMaker:
#!/bin/bash
# make file with :
# find .|grep jpg > wallpapers.txt
cd /home/houghi/wallpaper
for COUNT in `seq 2`
do
let COUNT=COUNT-1
LINES=$((`wc -l < wallpapers.txt`))
if [ $LINES -eq "0" ]
then
find .|grep jpg > wallpapers.txt
LINES=$((`wc -l < wallpapers.txt`))
fi
FILE=`head -$((($RANDOM * 32678 +$RANDOM) % $LINES + 1))
wallpapers.txt|tail -1`
grep $FILE -v wallpapers.txt > wallpapers.txt.bak
mv wallpapers.txt.bak wallpapers.txt
DISPLAY=:0.${COUNT} /usr/X11R6/bin/wmsetbg -a $FILE
# echo $COUNT $FILE
done
All pics are in /home/houghi/wallpaper in subdirectories. All are in
lowercase and have no spaces in them
The script first makes a wallpapers.txt file with all the files in it. It
then chooses a random line and does the wmsetbg for it. The DISPLAY in
front of it tells me what display to put it, so if you have just one
screen, loose the lines `for COUNT ...`, `do` and `done` and remove
`DISPLAY=:0.${COUNT}`.
If you have more then one desktop, you could change the `seq 2` to
whatever you have of amount and make it `DISPLAY=:${COUNT}.0 ...`
Next the script removes the line from the file, so it can be chosen the
next time.
Last but not least, put the script in crontab. Mine does a new screen
every 2 minutes. You can calculate how long I must watch before I have
seen all pics. :-)
I must say I do now see pictures that I previously have not seen in the
several months I had them and the other script was running.
