## SCP 常用命令
[关于scp传输文件踩过的坑(最全!linux与windows相互传输文件,连接失败,免密登录,连接超时) - 知乎](https://zhuanlan.zhihu.com/p/542926236)
### 基本语法
```shell
scp [可选参数] 源文件 目标文件

# 复制文件
scp local_file remote_username@remote_ip:remote_folder
scp local_file remote_username@remote_ip:remote_file

# 复制目录
scp -r local_folder remote_username@remote_ip:remote_folder

# 复制本地文件到远程服务器
scp file.txt user@192.168.1.100:/home/user/

# 复制远程文件到本地
scp user@192.168.1.100:/home/user/file.txt ./

# 复制整个目录
scp -r local_folder user@192.168.1.100:/home/user/

# 使用特定端口
scp -P 2222 file.txt user@192.168.1.100:/home/user/
