Q&A Can rsync handle moves and renames?

Improve fake `tree` output
  • Suppose I have a directory structure like
  • ```
  • ├── src
  • │   ├── folder_a
  • │   │   ├── file_w
  • │   │   ── file_x
  • │   ├── folder_b
  • │   │   ├── file_y
  • │   │   ── file_z
  • ```
  • and I back it up using `rsync`:
  • ```
  • $ rsync -r /path/to/src/ /path/to/dst/
  • ```
  • Later, I reorganize the contents of `src`, for example:
  • ```
  • ├── src
  • │   ├── folder_c
  • │   │   ├── file_w
  • │   │   ── file_y
  • │   ├── folder_d
  • │   │   ├── file_x
  • │   │   ── file_z
  • ```
  • Each file with a given name has not changed; but they don't have the same hierarchical relationship (i.e., files that used to be siblings might not be any more), and the names of their containing folders may have changed.
  • Can `rsync` detect that the `dst` folder contains the same files, and avoid copying files (instead only moving files within `dst` and renaming folders)? What options are useful to make this as smooth as possible?
