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:

-ccipher: Selects the cipher to use for encrypting the data transfer. This option is directly passed to ssh(1).
-iidentity_file: Selects the file from which the identity (private key) for RSA authentication is read. This option is directly passed to ssh(1).
-llimit: 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。
-Fssh_config: Specifies an alternative per-user configuration file for ssh. This option is directly passed to ssh(1).
-Pport: 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).
-Sprogram: Name of program to use for the encrypted connection. The program must understand ssh(1) options.
-ossh_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.
