SCP(1)

NAME
scp - 安全复制(远程文件复制程序)

总览 SYNOPSIS
scp [-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
scp 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), scp 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 scp 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_config(5). This is useful for specifying options for which there is no separate scp command-line flag.

-1  Forces scp to use protocol 1.

-2  Forces scp to use protocol 2.

-4  Forces scp to use IPv4 addresses only.

-6  Forces scp to use IPv6 addresses only.

DIAGNOSTICS
scp exits with 0 on success or >0 if an error occurred.
