scp - 安全复制(远程文件复制程序)

总览 SYNOPSIS

scp -words [-pqrvBC1246 ] [-F ssh_config ] [-S program ] [-P port ] [-c cipher ] [-i identity_file ] [-l limit ] [-o ssh_option ] [[user@ ] host1 : file1 ] [... ] [[user@ ] host2 : file2 ]

描述 DESCRIPTION

在网络中的主机间进行文件复制。它用 ssh(1) 来传输及验证数据，提供与 ssh(1)相同的安全保护。 它不象 rcp(1),会根据需要询问口令。

在任何文件名中都可以包含主机名和用户名，用来指定从/向该主机复制此文件。 Copies between two remote hosts are permitted.

The options are as follows:

-c cipher

Selects the cipher to use for encrypting the data transfer. This option is directly passed to ssh(1).

-i identity_file

Selects the file from which the identity (private key) for RSA authentication is read. This option is directly passed to ssh(1).

-l limit

Limits the used bandwidth, specified in Kbit/s.

-p

Preserves modification times, access times, and modes from the original file.

-r

递归复制整个目录。

-v

详细模式。该选项使 和 ssh(1) 打印出关于运行情况的调试信息。在进行调试连接、验证和配置问题时，这会很有用的

-B

用批模式(避免重复询问口令)。

-q

Disables the progress meter.

-C

允许压缩。向 ssh(1) 传递 -C 标志以允许压缩。

-F ssh_config

Specifies an alternative per-user configuration file for ssh This option is directly passed to ssh(1).

-P port

Specifies the port to connect to on the remote host. Note that this option is written with a capital `P' because -p is already reserved for preserving the times and modes of the file in rcp(1).

-S program

Name of program to use for the encrypted connection. The program must understand ssh(1) options.

-o ssh_option

Can be used to pass options to ssh in the format used in ssh_config5. This is useful for specifying options for which there is no separate scp command-line flag.

-1

Forces to use protocol 1.

-2

Forces to use protocol 2.

-4

Forces to use IPv4 addresses only.

-6

Forces to use IPv6 addresses only.
