First, what is SCP?

The SCP is a shorthand for secure copy, a command for remotely copying files under Linux, and a similar command with CP, although the CP is only copied natively and cannot cross the server, and the SCP transfer is encrypted. may have a slight effect on the speed.

Ii. What is the use of SCP?

1, we need to obtain a file on the remote server, the remote server does not configure the FTP server, does not open the Web server, and does not share, unable to obtain the file through the regular way, only through the SCP command can easily achieve the purpose. 2, we need to upload the file on the computer to the remote server, the remote server does not open the FTP server or share, can not be uploaded through the conventional way is, only through the SCP command to easily achieve the purpose.
