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.
This article will guide you 10 sftp command
examples to use it through interactive command-line interface.
1.
How to Connect to SFTP
By default, same SSH protocol is used to
authenticate and establish a SFTP connection. To start an SFTP session, enter
the username and remote hostname or IP address at the command prompt. Once
authentication successful, you will see a shell with an sftp> prompt.
[root@tecmint ~]# sftp tecmint@27.48.137.6
Connecting to 27.48.137.6...
tecmint@27.48.137.6's password:
sftp>
2.

available commands by typing ‘?‘ or ‘help‘ at command prompt.

Local working directory: /
sftp> pwd
Remote working directory: /tecmint/
- lpwd – print the current directory on your system
- pwd – print the current directory on the ftp server

Listing Files
Listing files and directories in local as well
as remote system.

Conclusion
The SFTP is a very useful tool for

We hope this tuts will help you to understand the usage of SFTP in some
