10 sFTP Command Examples to Transfer Files on Remote Servers in Linux

File Transfer Protocol (FTP) was widely used protocol to transfer files or data remotely in unencrypted format which is not secure way to communicate. As we all know that File Transfer Protocol is not at all secure because all transmissions happens in clear text and the data can be readable by anyone during sniffing the packets on the network.

So, basically FTP can be used in limited cases or on the networks that you trust. Over the period of time SCP and SSH addresses this security ambiguity and added an encrypted secure layer while transferring data between remote computers.

SFTP (Secure File Transfer Protocol) runs over SSH protocol on standard port 22 by default to establish a secure connection. SFTP has been integrated into many GUI tools (FileZilla, WinSCP, FireFTP etc.).

Security Warnings: Please don’t open SSH port (Secure SHell) globally as this would be a security breaches. You can only open for specific IP from where you are going to transfer or manage files on remote system or vice versa.
