¶ Transfer files
scp
scp (secure copy) command in Linux system is used to copy file(s) between servers in a secure way.
The SCP command or secure copy allows the secure transferring of files between the local host and the remote host or between two remote hosts.
It uses the same authentication and security as it is used in the Secure Shell (SSH) protocol.
You can copy files from a Windows terminal to a Linux system on the same LAN. Just make sure the Open SSH client is turned on and can be viewed in Settings > Applications > Optional Features.
If you want to copy files from Windows systems to Linux systems, you also need to enable the Open SSH server.
The scp command format is:
scp [optionals] file_source file_target-
[optionals] is an optional parameter, such as -r, which can be used to copy the entire directory recursively.
-
file_source The file or directory to be copied.
-
file_target will copy the past path and rename it if a specific file name is entered at the end.
Take copying local files from a Windows system to a Linux system as an example. In the Windows terminal, enter:
PS D:\temp\temp_4> scp ".\hello.txt" [email protected]:"/home/pi/Downloads/"You can also copy files in the Linux system to the local computer in the Windows terminal:
PS D:\temp\temp_4> scp [email protected]:"/home/pi/Downloads/hello.txt" "D:\temp\temp_4"-
Where [email protected] is the user name in the Linux system and the IP address of the BPI-M4 Zero in the LAN.
-
Where :"/home/pi/Downloads/hello.txt" is the file path in the Linux system.
-
Where "D:\temp\temp_4" is the path in Windows system. scp reference document
mobaxterm
Files can be managed through a graphical interface using mobaxterm or other similar software.
As shown in the figure below, after establishing an SSH connection in mobaxterm, a file management window will appear on the left side of the interface, which supports copying and pasting by dragging and dropping files.
