Automatically switching wallpapers is probably the best way to keep your desktop fresh and full of surprises. Of course, many apps can help you do this, but is it worth using an application for such an easy task?

What is is a Bash script that you can run on Linux to automatically find new wallpapers, downloading and switching them from Unsplash and various subreddits.

It is about a hundred lines of a shell script that uses wget to go and grab the wallpapers and download them to your machine. As you know, wget is a command-line download utility for Linux.

Since it is just a Bash script, you don’t need to install any packages or dependencies. You only need to have git installed on your machine.

./ -w 1920 -h 1200

Set a Wallpaper Based on a Search Term

You can use the -s option, which will perform an image search based on your search term. For multi-word search terms, enclose the words in double-quotes.

For example,  if you want to set a wallpaper showing an ocean sunset, type:

./ -s "ocean sunset"

Or you can search by a single word, in which case the quotes are not required.

./ -s birds

Automatically Change Wallpaper Every Hour via A Crontab

Cron is a scheduling daemon that executes tasks in the background at specified intervals. For example, using it, you can change your desktop wallpaper automatically.

To change the wallpaper every hour, launch the following command:

crontab -e

Now add the following to the opened file:

@hourly /path/to/script/

Save the file and exit. Make sure you replace /path/to/script/ with your actual path where your script is located.

This tells cron to set a random wallpaper every hour by running script. To customize or change this behavior, make sure to use the appropriate flags as per your requirements.
