Thank you, Ixp. I already looked at that. If that's the best DOpus can do regarding automating syncs I can keep on using FreeFileSync. Maybe @Leo or @Jon could consider this as a new feature request?
Note that each of the three commands should be run separately. The cannot be chained together to completely automate things, as the Find on line 1 is asynchronous. They let you automate each step, e.g. to do everything via hotkeys or avoid manually setting up the Synchronize panel, but you must wait for the comparison to finish (line 1) before you start the copy (line 2).
