Detailed analysis of the application of the Linux SCP Command (reproduced)

Transferred from: http://os.51cto.com/art/201003/187301.htm

The Linux SCP commands are used to copy files and directories between Linux, and how to use them here, from local replication to remote, remote replication to local, is two ways to use it. Here are specific examples:

==================

Linux SCP Command

==================

SCP can copy files between 2 Linux hosts;

Command basic format:

SCP [Optional parameters] File_source File_target

======

Copy from local to remote

======

* Copy files:

* Command format:

SCP Local_file [Email Protected]_ip:remote_folder

Or

SCP Local_file [Email protected]_ip:remote_file

Or

SCP Local_file Remote_ip:remote_folder

Or

SCP Local_file Remote_ip:remote_file

1th, 2 Specify the user name, command execution after the need to enter the password, the 1th only specifies the remote directory, the file name is unchanged, 2nd specified the file name;

3rd, 4 does not specify a user name, command execution after the need to enter a user name and password, the 3rd only specifies the remote directory, the file name is unchanged, 4th specified the file name;

Example

Scp/home/space/music/1.mp3 [Email Protected]:/home/root/others/music

Scp/home/space/music/1.mp3 [Email Protected]:/home/root/others/music/001.mp3

Scp/home/space/music/1.mp3 Www.cumt.edu.cn:/home/root/others/music

Scp/home/space/music/1.mp3 Www.cumt.edu.cn:/home/root/others/music/001.mp3

* Copy directory:

* Command format:

Scp-r Local_folder [Email protected]_ip:remote_folder

Or

Scp-r Local_folder Remote_ip:remote_folder

The 1th one specifies the user name, the command executes after the need to enter the password;

The 2nd does not specify a user name, the command will need to enter the user name and password after execution;

Example

Scp-r/home/space/music/[Email protected]:/home/root/others/

Scp-r/home/space/music/www.cumt.edu.cn:/home/root/others/

The above command copies the local music directory to the remote others directory, which is remotely available after replication. /others/music/Directory

======

Copy from remote to local

======

From remote copy to local, as long as the copy from the local to the remote command of the following 2 parameter Exchange order;

For example:

SCP [Email Protected]:/home/root/others/music/home/space/music/1.mp3

Scp-r www.cumt.edu.cn:/home/root/others//home/space/music/

The simplest applications are as follows:

SCP Local username @IP address: File name 1 remote user name @IP address: file name 2

[Local User name @IP address:] Can not be entered, you may need to enter the password for the remote user name.

Several parameters that may be useful:

-V is the same as-V in most Linux commands to show progress. Can be used to view connections, certifications, or configuration errors.

-C Enable compression option.

-P Select the port. Note-P has been used by RCP.

-4 forcibly use the IPV4 address.

-6 forcibly use the IPV6 address.

The use of Linux SCP commands should be able to satisfy everyone's use of the Linux file and directory replication.
