set Bing Wallpaper of the Day as your Linux Desktop's wallpaper

Script doesn't work on (K)ubuntu by default because of /bin/sh line #4

Closed fbcoder closed 6 years ago

fbcoder commented 10 years ago

In Ubuntu /bin/bash links to dash. For me the scripts only work if I change the first line to /bin/bash. If one runs the script as sh in Ubuntu there are errors on some specific bash syntax like the double square brackets for conditional statements.

Dear FBCODER and OAHONG:

Maybe this code helps.

Cheers,

Dani
