How the Linux sftp command is used, many beginners are not very clear about it. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can get something.

The concept of SFTP

Sftp is the abbreviation of Secure File Transfer Protocol, secure file transfer protocol. It can provide a secure network encryption method for transferring files. Sftp and ftp have almost the same syntax and function. SFTP is part of SSH and is a secure way to transfer files to a Blogger server. In fact, the SSH package already contains a secure file information transfer subsystem called SFTP (Secure File Transfer Protocol). SFTP itself does not have a separate daemon, it must use the sshd daemon (the port number is 22 by default) to complete the corresponding connection and reply operations, so in a sense, SFTP is not like a server program, but more like a client program. SFTP also uses encryption to transmit authentication information and transmitted data, so using SFTP is very secure. However, because this mode of transmission uses encryption / decryption technology, the transmission efficiency is much lower than ordinary FTP, if you have higher requirements for network security, you can use SFTP instead of FTP.

Here we use sftp to upload and download files on remote servers and local computers.

Usage:

Connect to the remote server:

Sftp username@ip

Enter the server password after entering the enter to connect successfully.

Upload the file to the server:

Put [address of local file] [location of file storage on the server]

Download the files on the server locally:

Get [location of file storage on the server] [location to be stored locally]

Get [location of file storage on the server] [location to be stored locally]

Finally, share a command in Linux that returns the directory above:
