Use: "tree remote:path",
|
|
Short: `List the contents of the remote in a tree like fashion.`,
|
|
Long: `
|
|
rclone tree lists the contents of a remote in a similar way to the
|
|
unix tree command.
|
|
|
|
For example
|
|
|
|
$ rclone tree remote:path
|
|
/
|
|
├── file1
|
|
├── file2
|
|
├── file3
|
|
└── subdir
|
|
├── file4
|
|
└── file5
|
|
|
|
1 directories, 5 files
|
|
|
|
You can use any of the filtering options with the tree command (eg
|
|
--include and --exclude). You can also use --fast-list.
|
|
|
|
The tree command has many options for controlling the listing which
|
|
are compatible with the tree command. Note that not all of them have
|
|
short options as they conflict with rclone's short options.
