I have worked on a file in Directory A. There is a file with the same name in directory B which is an older version of that same file. I rsync everything from B to A.
What happens to my work in the file in directory 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 :)
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.
