there are a gazillion switches to control the behavior. Like, --ignore-existing, to not overwrite any existing files ...
A becomes B. But... you have a lot of options in case you want a different behavior.
The actual use case: I have an emulator that uses a directory as the 'system disk' of the computer being emulated, but I have one of these on each of two machines. As I make updates I want to have the proper files updated on the other directory so between changes on the two emulators the most recent is synced to the other directory.
It seems I will need to use 2 rsync commands, one in each direction. Update A from B, then update B from A.
I have no idea what types of files these are but it could turn out that you should rather use Git and push/pull from both sides which could works better.
Just a suggestion :)
Linux
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
