Undo or fix a rename

Every rename writes .kettlemark-log.json in the folder. Kettlemark uses it to put names back.

Undo the last rename

kettlemark undo ~/Pictures/Goa

With --recursive, it undoes every folder inside too:

kettlemark undo ~/Pictures --recursive

If you renamed some files by hand

If you changed a few names yourself after Kettlemark ran, undo still works for the others. It skips any file it can't find under the name it gave it, and tells you which:

1,839 files restored.
3 not found (renamed or moved since): see the list above.

If you deleted the log

Without the log, Kettlemark can't know the old names. Restore the folder from a backup, or keep the new names. This is why the log stays in the folder until you undo.
