rclone dedupe

Interactively find duplicate files and delete/rename them.

Synopsis

By default dedupe interactively finds duplicate files and offers to delete all but one or rename them to be different. Only useful with Google Drive which can have duplicate file names.

In the first pass it will merge directories with the same name. It will do this iteratively until all the identical directories have been merged.

The dedupe command will delete all but one of any identical (same md5sum) files it finds without confirmation. This means that for most duplicated files the dedupe command will not be interactive. You can use --dry-run to see what would happen without doing anything.

Here is an example run.

Before - with duplicates

$ rclone lsl drive:dupes
  6048320 2016-03-05 16:23:16.798000000 one.txt
  6048320 2016-03-05 16:23:11.775000000 one.txt
   564374 2016-03-05 16:23:06.731000000 one.txt
  6048320 2016-03-05 16:18:26.092000000 one.txt
  6048320 2016-03-05 16:22:46.185000000 two.txt
  1744073 2016-03-05 16:22:38.104000000 two.txt
   564374 2016-03-05 16:22:52.118000000 two.txt

Now the dedupe session

$ rclone dedupe drive:dupes

The result being

Dedupe can be run non interactively using the --dedupe-mode flag or by using an extra parameter with the same value

• --dedupe-mode interactive - interactive as above.
• --dedupe-mode skip - removes identical files then skips anything left.
• --dedupe-mode first - removes identical files then keeps the first one.
• --dedupe-mode newest - removes identical files then keeps the newest one.
• --dedupe-mode oldest - removes identical files then keeps the oldest one.
• --dedupe-mode largest - removes identical files then keeps the largest one.
• --dedupe-mode smallest - removes identical files then keeps the smallest one.
• --dedupe-mode rename - removes identical files then renames the rest to be different.

For example to rename all the identically named photos in your Google Photos directory, do

rclone dedupe --dedupe-mode rename "drive:Google Photos"

Or

rclone dedupe rename "drive:Google Photos"

rclone dedupe [mode] remote:path [flags]

Options

      --dedupe-mode string   Dedupe mode interactive|skip|first|newest|oldest|largest|smallest|rename. (default "interactive")
  -h, --help                 help for dedupe

See the global flags page for global options not listed here.
