我没有在这台机器上安装Emacs ，但这是你可以做的：

1. http://www.gnu.org/s/emacs/manual/html_node/elisp/Standard-Hooks.html - 寻找 after-save-hook


2. 启动事情将转到您的 .emacs 文件 - 如果您在此文件末尾调用 org-mobile-pull ，则每次打开Emacs


3. 检查这个SO答案以进行定期运行的一些功能：如何定期在emacs中运行任务？

希望这有帮助。

I've recently started using MobileOrg (through Dropbox) to be able to manage my org-mode TODO lists while I'm away from my computer.

It's generally great, but the syncing back and forth has a few steps, so I'd like to try and simplify it a bit by automating the steps on the PC side.

Anyway, here are the two things I'd like to do:

1. Run org-mobile-push every time a file is saved, after the save completes. The only thing I use emacs for is org-mode, so this should be fine.
2. Run org-mobile-pull on emacs startup.
3. Run org-mobile-pull periodically, say every hour or so.

Thanks.

I don't have Emacs installed on this machine, but here's what you can do:

1. http://www.gnu.org/s/emacs/manual/html_node/elisp/Standard-Hooks.html - look for after-save-hook
2. Startup things go to your .emacs file - if you put the call to org-mobile-pull at the end of this file, you will have it run every time you open Emacs
3. Check this SO answer for a periodical run of some function: How to periodically run a task within emacs?

Hope this helps.
