Gnome and Changing Wallpaper by Time Automatically

Gnome and Changing Wallpaper by Time Automatically

Gnome users know that the wallpaper is same on all virtual desktop.To have different wallpapers on different workplace, you may try to use that little script, called Wallpapoz.
In this article, step by step, we will try to code our own script which changes wallpaper by time using crontab.First thing we have to do is to open gedit and copy/paste the code below into it:

#!/bin/bash

# wallpapers folder
pixfolder=”/home/$USER/wallpaper/
cd $pixfolder

# finding pix
files=(./*.jpg)

N=${#files[@]}
((N=RANDOM%N))

# choosing one of them
randomfile=`echo ${files[$N]} | cut –characters=”1 2″ –complement`

# changing wallpaper using gconftool
gconftool-2 -t str –set /desktop/gnome/background/picture_filename “$pix$randomfile”

Save the file as “changing.sh”

in terminal, run this command:

sudo cp changing.sh /bin/
sudo chmod +x /bin/changing.sh

Basically, you have a script named changing.sh which changes your wallpaper only when you run it.But we’d like the script to run automatically..This is where we use crontab.

in terminal, run this command to open crontab:

sudo crontab -e

in crontab editor copy/paste this:

*/1 * * * * changing.sh
@reboot changing.sh

then simply press ctrl+x and to save press y..

Thats it.If everythings fine, your wallpaper will be changing once per minute.

So enjoy your Wallpapers
