linux间文件拷贝

一 scp
scp就是secure copy,是用来进行远程文件拷贝的.数据传输使用ssh1,并且和ssh1使用相同的认证方式,提供相同的安全保证.
scp的基本用法可分为两种 ：
1、从本机给远程计算机拷贝文件
   命令格式为：  scp ［要拷贝的文件路径及文件名］ ［远程计算机用户名］＠［远程计算机的ip地址］：［远程计算机存放该文件的路径］
 2、从远程计算机拷贝文件到本机：
   命令格式：    scp [远程计算机用户名]＠［远程计算机ip地址］：［要拷贝的文件路径及文件名］  ［存放该文件的本机路径］

注意：
1 要是拷贝的是文件夹 ，则需要在scp命令后加 参数 -r 。
2 可以使用～/代替用户目录，但是文件路径需要的是完整路径。

具体的参数：

Options:
    -1' Force scp to use protocol 1.
    -2' Force scp to use protocol 2.
    -4' Force scp to use IPv4 addresses only.
    -6' Force scp to use IPv6 addresses only.
    -B' Select batch mode (dont ask for passwords or passphrases).
    -C' Compression, passes the -C flag to ssh(1) to enable compression.
    -c cipher
    Select 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
    Select the file from which the identity (private key) for RSA
    authentication is read. This option is directly passed to ssh(1).
    -l limit
    Limit 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
    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).

    -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 debugging connection, authentication, and configuration problems. 

scp退出参数：

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

实例：
Copy file1 to a remote host:
scp /home/simon/file1 kate@ss64.com:/home/kate

二 rcp 

三 同时也可以使用FTP

四 使用nfs server和client后mount到本地来实现文件的copy。

完！
