I would like my emacs to call
every 30 seconds and display whether Dropbox is up-to-date at the bottom of the buffer (where info such as the line-number and file name is).
How could I do this?
EDIT to add:
On my linux (with dropbox installed), the command line
dropbox status returns the Dropbox status:
$ dropbox status
Up to date
Unfortunately it seems like this doesn't work on OSX (https://superuser.com/questions/678925/using-dropbox-from-the-command-line-on-osx).
