Please help me to set wallpaper to all user client in ubuntu at same time.
 

hi,
I am working as a linux system administrator please help me to set a wallpaper to all client user at same time in ubuntu 16.04. I need commands and scripts.

And you also need to read the "Question Guidelines" link in my posting signature, as well as the LQ Rules. Do not come to a volunteer forum and DEMAND that we give you "commands and scripts". If you're the administrator, then you should have ideas on what to do...so post what you've done and tried so far, and tell us where you're stuck.

Otherwise, you can start by putting "how to set desktop wallpaper from command line in ubuntu" into Google. That will give you some commands to use. Since you are the 'administrator', you can script this however you'd like.

taking it off the top of my head, having even done this before, and you a linux system administrator, asking for something like this. not how to resolve a IP issue or such. how did you get that job? lucky I suppose.

you know you're going to have to be on the system side, you know it has to have something to do with log in perhaps, if it is upon the creation of a new user then that would require a different approach. Still having to use Root Admin, whenever someone login to there account certain files get sourced, use one of them to fire off a command that perhaps sets off a chain of events that in the end will set a desktop background image of your choosing, without taking into consideration that they, the use, can still change it. awful lot of work for it to be easily undone by a simple one liner off the command line.
