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!
