一、作用

  1. 在Linux下进行远程拷贝文件的命令

二、选项

  • -r 递归复制整个目录
  • -p 保留原文件的修改时间，访问时间和访问权限
  • -v 详细显示传输过程
  • -q 不显示传输进度条

    三、实例

    ```shell

    主机1 配置 IP地址：192.168.11.102/24

    [root@localhost ~]# mkdir /jhl/data [root@localhost ~]# [root@localhost ~]# cat >> /jhl/data/test1.txt <<EOF

    12321312 12312432 23131242 321321312 EOF
