## 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

564374 2016-03-05 16:22:52.118000000 two.txt
Now the `dedupe` session
$ rclone dedupe drive:dupes
2016/03/05 16:24:37 Google drive root 'dupes': Looking for duplicates using interactive mode.

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 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]
