Use: "dedupe [mode] remote:path",
Short: `Interactively find duplicate files delete/rename them.`,
Long: `
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

Now the ` + "`" + `dedupe` + "`" + ` session

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"
