Help with scipt to change wallpaper just before shutdown ?

Hi there!

I am not sure if this is the right place to post this question, but this was the only sub-forum I found with a reference to scripts.

I am running open-rc and would like to change my wallpaper (automatically) before shutdown, but  my searches result in almost exclusively systemd cases.

I will appreciate any tips, maybe links ?

Thanks in advance!

I guess you have to write openrc wallpaper_change script, put it in /etc/init.d and add it to shutdown runlevel:
Code: [Select]
sudo rc-update add wallpaper_change shutdown

@Ambie :  Thanks for prompt answer!   

This was exactly the info I was looking for. I will now  start looking into how  to write the script.

I wrote a script and placed it in ''/etc/init.d/':
Code: [Select]
~$ less /etc/init.d/byt_wallppr.sh
#!/bin/sh
sudo  xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitorLVDS1/workspace0/last-image -s /usr/share/backgrounds/xfce/paltanen.jpg

Tried to add it to shutdown runlevel:
Code: [Select]
~$  sudo rc-update add /etc/init.d/byt_wallppr.sh  shutdown
 * rc-update: service `/etc/init.d/byt_wallppr.sh' does not exist

changed perms:
Code: [Select]
$ sudo chmod 770 /etc/init.d/byt_wallppr.sh

still:
Code: [Select]
$  sudo rc-update add /etc/init.d/byt_wallppr.sh  shutdown
 * rc-update: service `/etc/init.d/byt_wallppr.sh' does not exist


Code: [Select]
~$ ls -l  /etc/init.d/byt_wallppr.sh 
-rwxrwx--- 1 root root 147 17 feb 21.56 /etc/init.d/byt_wallppr.sh

Don't know what. Is there anything wrong with my script? Have I missed any typo????????

Wonder whether it would be better to move this thread to subforum Open-rc and in that case how does one move it?

That's not a valid openrc script.

It needs to call openrc-run with the shebang a la
Code: [Select]
#!/usr/bin/openrc-run

This is one I use to call another script which sets up my fans at boot
Code: [Select]
#!/sbin/openrc-run

name=$RC_SVCNAME
command="/usr/local/bin/fanspeed"
command_args=""
pidfile="/run/${RC_SVCNAME}.pid"

depend() {
 	after modules
}
It could be better I guess as openrc complains about it at shutdown but it works.
It might make more sense to pick a new wallpaper at boot rather than shutdown as openrc will be terminating things and unmounting.
You could just use rc.local to run your command if you struggle with the script.
