WA.R.T. - WAllpaper RoTator (another one)

k3ttc4r · 2009-07-05 12:18:06

hi guys!

well, i know there already are a bunch of these around.. but i couldn't really find what i wanted, and i have like zero experience scripting bash. actually, this is pretty much my first script. it uses fbsetbg (can be changed pretty easily, though) to change my wallpaper every X minutes, or it can put a random wall every time it is executed. tell me what you think, and PLEASE let me know how i can improve it

#!/bin/sh

Perhaps you could combine it with that one, which is made for XFCE4 and works fine:

#!/bin/bash

export PATH="/sbin:/bin:/usr/sbin:/usr/bin"

ROTATEDELAY=120

WORKDIR=/tmp/.rotate_wallpaper

FILELIST=$WORKDIR/.imagefiles

# Location of the directories of your image files.
IMAGEFILES="$HOME/wallpapers"


if [ ! -d $WORKDIR ]
then
    mkdir $WORKDIR
fi

if [ -e FILELIST ]
then
    rm -f FILELIST
fi

# Build file list
for I in $IMAGEFILES
do
    find $I -type f \( -name '*.jpg' -o -name '*.png' -o -name '*.gif' \)>> $FILELIST
done

# Load list of images into array and remove unneeded file.
oIFS=$IFS IFS=$'\n' LINES=($(<"$FILELIST")) IFS=$oIFS
rm $FILELIST


# Pick random image, set the background, and loop forever.
cd $WORKDIR
while :
do
    n=${#LINES[@]}
    r=$((RANDOM % n))
    IMAGE="`echo ${LINES[r]}`"
    xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitor0/image-path -s ""
    xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitor0/image-path -s "${IMAGE}"
    killall -USR1 xfdesktop
    sleep $ROTATEDELAY
done

That one is using the regular means for setting the XFCE4 background (xfdesktop and xfconf).
KDE3/4 users do not need scripts for that, and while I'm not sure (not using Gnome) there are a couple of GNOME apps that can rotate the wallpaper.

sorry for barging in.
I am really new to the whole issue of xfce. I see the script that scarecrow posted. I however have no idea how to get it to run while i am in xfce. Could you please explain how to do this. Sorry if this seems like a noobie thing.
