## 项目简介
2018-10-30 17:45:30 +08:00
本项目是基于golang标准库 ssh 和 sftp 开发
本项目是对标准库进行一个简单的高层封装,使得可以在在 Windows Linux Mac 上非常容易的执行 ssh 命令,
以及文件,文件夹的上传,下载等操作.

1. 当src 为目录时
````bash
文件上传下载模仿rsync: 只和源有关.
// rsync -av src/ dst ./src/* --> /root/dst/*
// rsync -av src/ dst/ ./src/* --> /root/dst/*
// rsync -av src dst ./src/* --> /root/dst/src/*
// rsync -av src dst/ ./src/* --> /root/dst/src/*
````

2. 当src 为文件时
2018-11-13 17:42:29 +08:00
当dst为目录以"/"结尾,则自动拼接上文件名
当dst为文件不以“/”结尾时,则重命名文件

## Install
`go get gitee.com/yuzhen-iot-team/ssh`

## Example
### 在远程执行ssh命令
提供3个方法: Run() Exec() Output()
2018-12-19 14:33:31 +08:00
1. Run() : 程序执行后,不再受执行者控制. 适用于启动服务端进程.
2. Exec() : 在控制台同步实时输出程序的执行结果.
3. Output() : 会等待程序执行完成后,输出执行结果,在需要对执行的结果进行操作时使用.
