NAME
     scp - secure copy (remote file copy program)

SYNOPSIS
     scp [-1246BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file]
         [-l limit] [-o ssh_option] [-P port] [-S program]
         [[user@]host1:]file1 [...] [[user@]host2:]file2

DESCRIPTION
     scp copies files between hosts on a network.  It uses ssh(1) for
     data transfer, and uses the same authentication and provides the
     same security as ssh(1).  Unlike rcp(1), scp will ask for passwords
     or passphrases if they are needed for authentication.

     Any file name may contain a host and user specification to indicate
     that the file is to be copied to/from that host.  Copies between
     two remote hosts are permitted.

     When copying a source file to a target file which already exists,
     scp will replace the contents of the target file (keeping the
     inode).

     If the target file does not yet exist, an empty file with the tar-
     get file name is created, then filled with the source file con-
     tents.  No attempt is made at "near-atomic" transfer using tempo-
     rary files.

     The options are as follows:

     -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.

     -B      Selects batch mode (prevents asking for passwords or
             passphrases).

     -C      Compression enable.  Passes the -C flag to ssh(1) to enable
             compression.

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

     -F ssh_config
             Specifies an alternative per-user configuration file for
             ssh.  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.
  -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.  For full
             details of the options listed below, and their possible
             values, see ssh_config(5).

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

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

     -q      Disables the progress meter.

     -r      Recursively copy entire directories.

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

     -v      Verbose mode.  Causes scp and ssh(1) to print debugging
             messages about their progress.  This is helpful in debug-
             ging connection, authentication, and configuration prob-
             lems.

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

HISTORY

     Regents of the University of California.

名字             
 安全复制（远程文件复制程序）             

简介             
 scp [-1246bcpqrv][-c密码][-f ssh配置][-i标识文件]             
  [-l限制][-o ssh_选项][-p端口][-s程序]             
  [[user@]host1:]file1[…][[user@]host2:]file2
  
描述             
 SCP在网络上的主机之间复制文件。它使用ssh（1）进行数据传输，
 并使用相同的身份验证，并提供与ssh（1）相同的安全性。
 与RCP（1）不同，如果认证需要密码或密码，SCP将询问它们。              
 
 任何文件名都可以包含主机和用户规范，以指示文件将被复制到该主机或从该主机复制。允许在两个远程主机之间复制。
 
 将源文件复制到已存在的目标文件时，SCP将替换目标文件的内容（保留索引节点）。             
 
 如果目标文件尚不存在，将创建一个具有目标文件名的空文件，然后用源文件内容填充。未尝试使用临时文件进行“近原子”传输。
 选项如下：             
 -1   强制SCP使用协议1。             
 -2   强制SCP使用协议2。             
 -4   强制SCP仅使用IPv4地址。             
 -6   强制SCP仅使用IPv6地址。             
 -B   选择批处理模式（防止询问密码或口令）             
 -C   压缩启用。将-c标志传递给ssh（1）以启用压缩。             
 -c   密码
      选择用于加密数据传输的密码。此选项直接传递给ssh（1）。
 -F  配置SSH
   应该提醒用户配置文件通过一个SSH。这个选项是直接传递到SSH的（1）。
 -I   身份文件             
      选择从中读取RSA身份验证标识（私钥）的文件。此选项直接传递给ssh（1）。
    -l   限制           
      限制使用的带宽，以kbit/s为单位。
 -o   ssh_选项             
   可用于以ssh_config（5）中使用的格式将选项传递给ssh。这对于指定没有单独SCP命令行标志的选项很有用。
   有关下面列出的选项及其可能值的完整详细信息，请参阅ssh_config（5）。

 -P  端口             
   指定要连接到远程主机上的端口。注意这个选项是用大写字母写的吗？？。
   因为-p已经被保留用于在RCP（1）中保留文件的时间和模式。
 -p              保留原始文件中的修改时间、访问时间和模式。
 -q  禁用进度表。
 -S  程序
            用于加密连接的程序名称。程序必须理解ssh（1）选项。
    -v      冗长模式。使scp和ssh（1）打印有关进度的调试消息。这有助于调试连接、身份验证和配置问题。
诊断模式            
 成功时SCP退出0，如果发生错误，则大于0。
