SFTP is a secure file transfer protocol used popularly in Linux to transfer files. It is much better than normal FTP as it encrypts data during transmission and prevents it from being deciphered by network sniffers. SFTP runs over SSH protocol to use a secure connection, and is also a part of popular FTP services such as FileZilla, WinSCP, FireFTP, etc. In this article, we will look at the top SFTP command examples to work with SFTP.

In this article, we have learnt many different commands to work with SFTP. Basically, most of these commands are similar to the ones used in Linux shell/terminal. E.g cd command changes directory. For most of these commands there are two counterparts – one for local machine and the other for remote machine. The remote command is similar to the Linux command (e.g cd changes remote directory), and its local counterpart can be obtained by prefixing ‘l’ (letter el) to the remote command (e.g lcd changes local directory).
