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.
