   #!/bin/bash
   
   # Google Drive sharing link for the image
   image_path_link="https://drive.google.com/uc?export=download&id=YOUR_FILE_ID_HERE"
   
   # Fetch the username of the user who invoked the script
   username=$(logname)
   
   # Destination directory for the downloaded image (Downloads folder)
   destination_dir="/home/$username/Downloads"
   
   # File name for the downloaded image
   # please replace the file_name by the desired wallpaper name to be set for downloaded image file
   file_name="image.jpg"
   
   # Maximum number of download attempts
   max_attempts=3
   
   # Function to download the image
   download_image() {
       local attempt=1
       while [ $attempt -le $max_attempts ]; do

           if curl -k -L -o "$destination_dir/$file_name" "$image_path_link"; then

   download_image
   
   # Define the path to the downloaded wallpaper image
   WALLPAPER_PATH=$(realpath "$destination_dir/$file_name")
   
   # Set the wallpaper for all users
   for user in $(getent passwd | cut -d: -f1); do
       # Get the user's home directory
       user_home=$(eval echo ~$user)
   
       # Set the wallpaper for the user
       sudo -u $user DISPLAY=:0 DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/$(id -u $user)/bus gsettings set org.gnome.desktop.background picture-uri "file://$WALLPAPER_PATH"
   done
   
   # Revoke permission to the X server after setting wallpaper
   xhost -SI:localuser:$(whoami)

3. In the script, replace the following placeholder:

   1. Please make sure that the image file is accessible to all.

   2. Add the File ID in the script.
      # Google Drive sharing link for the image

      image_path_link="https://drive.google.com/uc ?export=download&id=YOUR_FILE_ID_HERE"

   3. To obtain the file ID for a file hosted on Google Drive, follow these steps:

      1. Open Google Drive: Go to Google Drive and log in to your Google account if you're not already logged in.

      2. Locate the File: Find the file you want to share or download.

      3. Get the File ID: Right-click on the file and select "Get link" from the menu. Alternatively, you can click on the file to open it, and then the file ID will be visible in the URL in the address bar of your browser. The file ID typically appears after the id= parameter in the URL.

      4. For example,
         https://drive.google.com/file/d/1AhzJz5y6v589WvexxxxxxxxxxxUhc48XfQD/view?usp=drive_link

      5. File ID is the alphanumeric string in the URL.
