Copy files from one drive to another, keeping most recently modified files
Hi all, I am a bit of a beginner with shell scripting..
What I want to do is merge two drives, for example moving all data from X to Y.
If a file in X doesn't exist in Y, it will be moved there.
If a file in X also exists in Y, the most recently modified file will be moved to (or kept) in Y.
I have done some reading on the forums and it seems rsync could be helpful, but the most important factor in this exercise is to only keep the most recently modified file, which I am not sure rsync does...
Do any of you have any recommendations? Thanks for the help!
