scp是secure copy的简写,用于在Linux下进行远程拷贝文件的命令,和它类似的命令有cp,不过cp只是在本机进行拷贝不能跨服务器,而且scp传输是加密的。可能会稍微影响一下速度。当你服务器硬盘变为只读 read only system时,用scp可以帮你把文件移出来。另外,scp还非常不占资源,不会提高多少系统负荷,在这一点上,rsync就远远不及它了。虽然 rsync比scp会快一点,但当小文件众多的情况下,rsync会导致硬盘I/O非常高,而scp基本不影响系统正常使用。 1.命令格式: 2.命令功能: 3.命令参数: 4.使用实例: (1) 复制文件: 复制代码 代码如下:scp local_file <a href="mailto:remote_username@remote_ip:remote_folder">remote_username@remote_ip:remote_folder</a> 或者 scp local_file <a href="mailto:remote_username@remote_ip:remote_file">remote_username@remote_ip:remote_file</a> 或者 scp local_file remote_ip:remote_folder 或者 scp local_file remote_ip:remote_file 第1,2个指定了用户名,命令执行后需要输入用户密码,第1个仅指定了远程的目录,文件名字不变,第2个指定了文件名 第3,4个没有指定用户名,命令执行后需要输入用户名和密码,第3个仅指定了远程的目录,文件名字不变,第4个指定了文件名 (2) 复制目录: 复制代码 代码如下:[root@localhost ~]# cd /opt/soft/ [root@localhost soft]# ll 总计
