I have a USB stick that I want to copy all files and folders from the USB stick to my OneDrive account to get the newest files out there. I want to copy all folders and files that are newer (updated most recently) from Volumes/BAUERBKUP/Documents/College/Capella to /Users/dbauer/Desktop/OneDrive/Documents/Capella I also want to do the reverse and backup all files from the OneDrive account to my USB stick and assume the commands are the same just switching the locations. How do I do this on a Mac OS X? I do scripts in Windows but never on a Mac and have no clue where to even start. If this is not the right place for this question, tell me where to post this and I will.
