Use: "dedupe [mode] remote:path",
|
|
Short: `Interactively find duplicate filenames and delete/rename them.`,
|
|
Long: `
|
|
|
|
By default ` + "`dedupe`" + ` interactively finds files with duplicate
|
|
names and offers to delete all but one or rename them to be
|
|
different. This is known as deduping by name.
|
|
|
|
Deduping by name is only useful with a small group of backends (e.g. Google Drive,
|
|
Opendrive) that can have duplicate file names. It can be run on wrapping backends
|
|
(e.g. crypt) if they wrap a backend which supports duplicate file
|
|
names.
|
|
|
|
However if --by-hash is passed in then dedupe will find files with
|
|
duplicate hashes instead which will work on any backend which supports
|
|
at least one hash. This can be used to find files with duplicate
|
|
content. This is known as deduping by hash.
|
|
|
|
If deduping by name, first rclone will merge directories with the same
|
|
name. It will do this iteratively until all the identically named
|
|
directories have been merged.
|
|
|
|
Next, if deduping by name, for every group of duplicate file names /
|
|
hashes, it will delete all but one identical files it finds without
|
|
confirmation. This means that for most duplicated files the ` +
|
|
"`dedupe`" + ` command will not be interactive.
|
|
|
|
` + "`dedupe`" + ` considers files to be identical if they have the
|
|
same file path and the same hash. If the backend does not support hashes (e.g. crypt wrapping
|
|
Google Drive) then they will never be found to be identical. If you
|
|
use the ` + "`--size-only`" + ` flag then files will be considered
|
|
identical if they have the same size (any hash will be ignored). This
|
|
can be useful on crypt backends which do not support hashes.
|
|
|
|
Next rclone will resolve the remaining duplicates. Exactly which
|
|
action is taken depends on the dedupe mode. By default rclone will
|
|
interactively query the user for each one.
|
|
|
|
**Important**: Since this can cause data loss, test first with the
|
|
` + "`--dry-run` or the `--interactive`/`-i`" + ` flag.
|
|
|
|
Here is an example run.

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.
|
|
* ` + "`" + `--dedupe-mode list` + "`" + ` - lists duplicate dirs and files only and changes nothing.

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"
