I would like to update Google Calendar / iCal automatically by exporting my org deadlines and scheduled tasks in .ics format, then automatically importing them into a cross-platform calendar app. I have tried the org / Google Calendar integration and been unable to get it to work. Is it possible to use cron jobs or some other method to automate this task?
Update: I have used org-icalendar-export-to-ics to export my org file and then manually imported it into the OSX calendar app, and it then appears in my Google Calendar. I am wondering whether anyone has a way to automate this process. As a first step, I envision running a command from the terminal that launches emacs with an argument that sends the org-icalendar-export-to-ics command. Is that possible? After that, I'll have to set up a way to automatically import the .ics file into either OSX calendar or Google Calendar.
