sftp
|
||||
----
|
||||
|
||||
The `sftp` package provides support for file system operations on remote ssh servers using the SFTP subsystem.
|
||||
|
||||
[](https://travis-ci.org/pkg/sftp) [](http://godoc.org/github.com/pkg/sftp)
|
||||
|
||||
usage and examples
|
||||
------------------
|
||||
|
||||
See [godoc.org/github.com/pkg/sftp](http://godoc.org/github.com/pkg/sftp) for examples and usage.
|
||||
|
||||
The basic operation of the package mirrors the facilities of the [os](http://golang.org/pkg/os) package.
|
||||
|
||||
The Walker interface for directory traversal is heavily inspired by Keith Rarick's [fs](http://godoc.org/github.com/kr/fs) package.
|
||||
|
||||
roadmap
|
||||
-------
|
||||
|
||||
* There is way too much duplication in the Client methods. If there was an unmarshal(interface{}) method this would reduce a heap of the duplication.
|
||||
|
||||
contributing
|
||||
------------
|
||||
|
||||
We welcome pull requests, bug fixes and issue reports.
|
||||
|
