Today I will show you how Linux copies files remotely. The content of the article is good. Now I would like to share it with you. Friends who feel in need can understand it. I hope it will be helpful to you. Let's read it along with the editor's ideas.

Scp is the abbreviation of secure copy, which is a secure remote file copy command based on ssh login in Linux system. Its main function is to copy files and directories between Linux servers.

1. Copy the entire local / home/administrator/test directory to the / root directory of the remote host 192.168.1.100.

The code is as follows:

Scp-r / home/administrator/test/ root@192.168.1.100:/root/2, copy a single file to a remote host

The code is as follows:

In fact, the difference between uploading files and folders in scp / home/administrator/test/test.txt root@192.168.1.100:/root/ lies in the parameter-r, which is similar to that of cp and rm. There are more than one-r for text price increase.

3. Download remote files / folders

For example, download the / root/ folder above 192.168.0.10 to the local / home/administrator/new/ and log in using the root on the remote side

The code is as follows:

Detailed explanation of scp-r root@192.168.1.100:/root/ / home/administrator/newscp command

Syntax:

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 is easy to write:

Scp [optional parameters] file_source file_target parameter description:

-1: force the scp command to use the protocol ssh2

-2: force the scp command to use the protocol ssh3

-4: forces the scp command to use only IPv4 addressing

-6: force the scp command to use only IPv6 addressing

-B: use batch mode (transfer passwords or phrases are not asked during transfer)

-C: compression is allowed. (pass the-C flag to ssh to turn on compression)

-p: retain the modification time, access time and access rights of the original file.

-Q: the transmission progress bar is not displayed.

-r: copy the entire directory recursively.

-v: display the output in detail. Scp and ssh (1) show debugging information for the entire process. This information is used to debug connections, verify, and configure problems.

-c cipher: encrypts the data transfer in cipher, this option will be passed directly to ssh.

-F ssh_config: specify an alternate ssh configuration file, which is passed directly to ssh.

-I identity_file: reads the key file used for transfer from the specified file, and this parameter is passed directly to ssh.

-l limit: limits the bandwidth that users can use, in Kbit/s.

-o ssh_option: if you are accustomed to using the parameter passing method in ssh_config (5)

-P port: note that it is capitalized P, and port is the port number used to specify the data transfer.

-S program: specifies the program to be used for encrypted transmission. This program must be able to understand the options of ssh (1)
