     scp - 安全复制(远程文件复制程序)

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

     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。

     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

     -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 scpssh(1)

     -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

     -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.


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

     scp 基于University of California BSD 的 rcp(1) 源代码

     rcp(1), sftp(1), ssh(1), ssh-add(1), ssh-agent(1), ssh-keygen(1),
