scp(secure copy)是基于ssh的安全拷贝命令，scp常用的参数如下：
-2：Forces scp to use protocol 2. #基于ssh协议2文 章 源 自 note.t4x.orgByrd's Blog-https://note.t4x.org/basic/ssh-secure-copy/
-4：Forces scp to use IPv4 addresses only. #基于TCP/IP ipv4协议文 章 源 自 note.t4x.orgByrd's Blog-https://note.t4x.org/basic/ssh-secure-copy/
-P：port #接端口号文 章 源 自 note.t4x.orgByrd's Blog-https://note.t4x.org/basic/ssh-secure-copy/
-p：Preserves modification times, access times, and modes from the original file. #保持文件或者目录的最后一次修改时间、属性。文 章 源 自 note.t4x.orgByrd's Blog-https://note.t4x.org/basic/ssh-secure-copy/
-r：Recursively copy entire directories. #递归整个目录文 章 源 自 note.t4x.orgByrd's Blog-https://note.t4x.org/basic/ssh-secure-copy/
-v：Verbose mode. #debug模式文 章 源 自 note.t4x.orgByrd's Blog-https://note.t4x.org/basic/ssh-secure-copy/

ok，到此结束。主要参数实际上也没有几个吧？-P接端口，-p是文件属性，-r是递归。文 章 源 自 note.t4x.orgByrd's Blog-https://note.t4x.org/basic/ssh-secure-copy/
