本文介绍了Linux scp命令的使用，包括从本地到远程以及从远程到本地的文件和目录拷贝。通过示例详细展示了scp命令的语法和常用参数，如-v（显示进度）、-C（启用压缩）、-P（选择端口）等，帮助用户在不同Linux主机间安全地传输文件。

Linux scp命令用于Linux之间复制文件和目录

scp [可选参数] file_source file_target

1)本地到远程

A)文件

scp local_file remote_username@remote_host:remote_file

scp local_fle remote_host:remote_file

[root@localhost ~]# scp ./sh/corn.sh weizong@192.168.0.251:/home/weizong/
weizong@192.168.0.251's password:
corn.sh 100% 480 0.5KB/s 00:00

B)目录

scp -rv local_dir remote_username@remote_host:remote_dir

scp -rv local_dir remote_host:remote_dir

scp -rv /var/develop/ weizong@192.168.0.251:/home/weizong/
