## Description
|
||||
The `pfs` command is a Command Line Interface to manage your files on PaddlePaddle Cloud
|
||||
|
||||
## Synopsis
|
||||
```
|
||||
paddle [options] pfs <subcommand> [parameters]
|
||||
```
|
||||
|
||||
## Options
|
||||

|
||||
|
||||
## Path Arguments
|
||||
When using a command, we need to specify path arguments. There are two path argument type: `localpath` and `pfspath`.
|
||||
|
||||
A `pfspath` begin with `/pfs`, eg: `/pfs/$DATACENTER/home/$USER/folder`.
|
||||
|
||||
[Here](https://github.com/PaddlePaddle/Paddle/blob/develop/doc/design/cluster_train/data_dispatch.md#上传训练文件) is how to config datacenters.
|
||||
|
||||
## order of Path Arguments
|
||||
Commonly, if there are two path arguments, the first is the source, and the second is the destination.
|
||||
|
||||
## Subcommonds
|
||||
- rm - remove files or directories
|
||||

||||
Synopsis:
|

||||
|
||||
Options:
|
||||
-r
|
||||
Remove directories and their contents recursively
|
||||
-v
|
||||
Cause rm to be verbose, showing files after they are removed.
|
||||
|
||||
Examples:
|
||||
paddle pfs rm /pfs/$DATACENTER/home/$USER/file
|
||||
paddle pfs rm -r /pfs/$DATACENTER/home/$USER/folder
|
||||
```
|
||||
- mv - move (rename) files
|
||||

|
||||
Synopsis:

|
||||
mv [-f | -n] [-v] <PFSPath> <LocalPath>
