## rclone dedupe
Interactively find duplicate files delete/rename them.
### Synopsis
By default `dedup` 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.
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

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
```
