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.

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 ``` ### Options ``` --dedupe-mode string Dedupe mode interactive|skip|first|newest|oldest|rename.
