Recommended random wallpaper program using feh won't work


The following program from wiki.Debian.org/openbox is shown under "Setting your background image with feh" (random wallpaper), but for me it comes up with error messages.

Code:
#wallpaper.sh
WALLPAPERS="~/wallpapers"
ALIST=( 'ls -wl ~/wallpapers' )
RANGE=${#ALIST[@]}
let "number=$RANDOM"
let LASTNUM="'cat $WALLPAPERS/.last' + number"
let "number=$LASTNUM % $RANGE"
echo $number > $WALLPAPERS/.last

feh --bg-scale $WALLPAPERS/${ALIST[$number]}
Here are the error messages, which seem to say that /.last is not valid.
Is that right? If so, how to fix?

Code:
feh --bg-scale $WALLPAPERS/${ALIST[$number]}
./wallpaper.sh: line 7: let: LASTNUM='cat ~/wallpapers/.last' + number: syntax error: operand expected (error token is "'cat ~/wallpapers/.last' + number")
./wallpaper.sh: line 8: let: number= % 1: syntax error: operand expected (error token is "% 1")
./wallpaper.sh: line 9: ~/wallpapers/.last: No such file or directory
feh WARNING: ~/wallpapers/ - File does not exist
feh ERROR: Couldn't load image in order to set bg

Well for starters specifying ~/wallpapers in both of these lines

Code:
WALLPAPERS="~/wallpapers"
ALIST=( 'ls -wl ~/wallpapers' )
is daft. The second line should use the WALLPAPERS variable.

The script as you post it won't work because you're using ' where you should be using `

Also the script is way more complicated than it needs to be. Try this.

Code:
!#/bin/bash
WALLPAPERS="${HOME}/wallpapers"
cd "${WALLPAPERS}"
feh --bg-scale "$(ls | sort -R | head -1)"
You could reduce that by a line by not using the WALLPAPERS variable.

Cool random wallpaper

I don't have a clue on what you asked, but I have been using a gui program called "Desktop Nova" along with "Desktop Nova-Tray. You can set up to get Wallpaper from various files and can tell it to randomize it. Can also set up the period between each graphic. I am using photos in two groups and it works wonderfully. Hope this helps you

The short program offered by Arizonagroovejet (reduced to two lines as suggested) works perfectly for me, so I'll stay with that. You caught me in a syntax error with the longer program from the wiki ( ' that should be ` ), but I still did not get it to work.
To reply to andrewthomas:

iDesk is great for that and very lightweight.

Unfortunately it seems its wiki is down (maybe forever?).
But a while ago I wrote some instructions to set it in antiX's faq in Brazilian Portuguese. Maybe you could translate it with google: http://sblinux.org/antix-port/#Como_...fundo_de_tela_
Below is a sample conf file for the rotating background form ~/Wallpaper every 1 minute:
Code:
  Background.File: image.jpg
  Background.Delay: 1
  Background.Source: ~/Wallpaper
  Background.Mode: Scaled
  Background.Color: #C2CCFF
To have a fixed image, leave 'Background.Source:' empty and put the image path in 'Background.File:'.
antiX, it seems, doesn't come anymore with idesk and its GUI config tool but I'll try and find out wich one it used.

Here are some GUI tools for idesk:
http://crunchbanglinux.org/forums/to...desk-tool-gui/
http://fixxxer.mx/blog-en/?p=6
http://icecc.sourceforge.net/idesktools.html

antiX used to use tidesktool and it worked fine.

To recap, i.e. How to program Random Wallpapers with feh:
With wallpaper images filed in a file called wallpapers in one's home directory, use the following two commands:

cd ~/wallpapers
feh --bg-scale "$(ls / sort -R / head -1)" &

I have these in my autostart file (~/.config/openbox/autostart.sh) followed by any other commands desired on startup
