The 4th commands specify the file name. * example: scp/home/space/music/1.mp3 root@www.cumt.edu.cn:/home/root/others/music scp/home/space/music/1.mp3 root@www.cumt.edu.cn: /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 from remote to local

From remote to local, you only need to replace the last two parameters of the local command to remote;

For example:
Scp root@www.cumt.edu.cn:/home/root/others/music/home/space/music/1.mp3
Scp-r www.cumt.edu.cn:/home/root/others/home/space/music/
The simplest application is as follows:

Scp Local User Name @ IP Address: file name 1 remote user name @ IP Address: file name 2

[Local username @ IP Address:] You may not need to enter the password corresponding to the remote username.

Several useful parameters:

-V is the same as-v in most linux commands. It is used to display the progress. It can be used to view the connection, authentication, or configuration error.

-C enable compression options.

-P: select the port. Note that-p has been used by rcp.

-4 Use the IPV4 address forcibly.

-6 Use IPV6 addresses forcibly.
