I wrote a little script that grabs a random wallpaper from the Desktoppr API and changes my desktop wallpaper to it:
#!/bin/bash url=$(curl 'https://api.desktoppr.co/1/wallpapers?page='$(shuf -i 1-1000 -n 1) | jq ".response.image.url" | sed $(shuf -i 1-20 -n 1)'!d') && wget "$url"
When I run the script, the final
wget command fails with the error:
"http://a.desktopprassets.com/wallpapers/...jpg": Scheme missing.
When I put the URL directly into the wget command, like so:
... the command executes correctly and downloads the image, meaning that the error occurs because of some problem in the variable.
I think this might have something to do with the
jq library that I am using to parse the JSON response from the Desktoprr API.
