Bash background changing script
 

Hey internet people i have been trying to create a bash script that will change my desktop background, boot splash image, and the gdm3 login background. If one of you could write it for me or atleast point me in the right direction i would greatly appreciate it. Im currently running tango studio (based on debian)
