Mac Emacs SKK file sharing
Rsync command does not download even if upload directory contents are newer than source contents. Is this caused by bad option? I have no idea.
But, I found more easier resolution with GoogleDrive. The step is below.
I use emacs under this environment. If there would be some problem, I have to consider. I will try git repository on the host which has a global static IP address and manage my contents using the git.
