Editor to share with you how to use the SCP command in Linux to transfer files safely. I believe most people don't know much about it, so share this article for your reference. I hope you will get a lot after reading this article. Let's go and learn about it.

SCP (Secure Copy) is a command-line tool for Linux systems that securely transfers files from local to remote servers, and vice versa. SCP uses the SSH protocol to transfer files between two systems, which is more secure than ftp.

Syntax: (local to remote)

Scp / path/to/local/file.txt user@192.168.10.100: / remote / path/

Syntax: (remote to local)

Scp user@192.168.10.100: / remote/file.txt / path / to / local /

The SCP command requires the password of the remote system. If you need to configure scp commands in a script and run using scheduler, you need to configure a key-based ssh login.

Transfer files locally to a remote server

The following command will use root authentication to copy myfile.txt from the current directory on the local system to the / opt directory of the remote server. We assume that the hostname of the remote server is example.com.

$scp myfile.txt root@example.com:/opt/

Transfer files from a remote server to the local

The following command will copy / opt/myfile.txt from the remote system to the / opt directory on the local system.

$scp root@example.com:/opt/myfile.txt / opt/

Define a port with the scp command

If ssh is running on a different port on the remote server, use the-p switch followed by the port number and the scp command.

If SSH is running on a different port on the remote server, use the-P switch, and then use the scp command to use the port number.

$scp-P 2344 myfile.txt root@example.com:/opt/myfile.txt

Recursively transfer the directory locally to the remote server

The following command will recursively copy the / opt / mydir directory from the local system to the / opt directory of the remote system.

$scp-r / opt/mydir root@example.com:/opt/

Recursively transfer the directory remote server to the local

The following command will copy the / opt/mydir directory recursively from the remote system to the / opt directory of the remote system

The above $scp-r root@example.com:/opt/mydir / opt/ is all the contents of the method of safely transferring files using the SCP command in Linux. Thank you for reading!
