We are all familiar with the FTP protocol and if you are reading this article you’ve probably used it for transferring files to your virtual server and your local computer. FTP is very simple protocol, but it is also very insecure. All transmissions, including the username and password, are transferred in clear text and it does not use any type of security or encryption while transferring the data. It means that all data can be read by anyone who may intercept the transmission. Luckily, there is a great replacement for the FTP protocol – SFTP.

SFTP stands for Secure File Transfer Protocol and it relies on SSH. SFTP allows users to transfer data over a connection that is secured using the well known Secure Shell (SSH) protocol. The SFTP protocol is also faster and uses less data than the FTP protocol. Therefore we highly recommend using SFTP instead of FTP whenever possible. You can transfer your files between your machines using some of the popular SFTP clients such as FileZilla, Cyberduck or WinSCP. You can also do it directly from the Linux command line.

In this article, we will list and explain some of the most popular and useful SFTP commands. They are great for beginners – easy to understand and useful for everyday server tasks.

1. Connect to the SFTP server

You can connect to a remote server via SFTP using the following command

sftp  user@IP_Address

user@IP_Address' password:
Connected to IP_Address.

You can also use a hostname instead of the IP address.

We already mentioned that SFTP is using the same protocol as SSH, so if SSH is not listening on the default port 22, you can specify the port in the command

sftp -oPort=2345 user@IP_Address

Where ‘2345’ is the port number you are using.

2. List all files in the current directory

Using the ls command you can list all files and directories in the current working directory

sftp> ls
directory directory1  file  file.txt file.zip

You can also list the files on the local system

sftp> lls

3. Navigate through directories

To find the current working directory on the local server use

sftp> pwd
Remote working directory: /home/user

for the local server use the following command

sftp> lpwd
Local working directory: /

You can easily change the working directory in SFTP. For the remote server use

sftp? cd directory

and for the local server use

sftp> lcd directory

4. Upload files and directories using the put command

You can upload single or multiple files or directories from the local machine to the remote one.

sftp> put filename

To upload multiple files use the following command

sftp> mput file1 file2 file3

To upload a directory to the remote server, you have to create the destination directory on the remote server first, and then start the upload

sftp> mkdir directory
sftp> put -r directory/

5. Download files and directories using the get command

Download a single file from the remote to the local machine

sftp> get file

or download multiple files with the ‘mget’ command

sftp> mget file1 file2 file3

Download a directory and all its content with the following command

sftp> get -r directory

6. Create and remove directories

Create a new directory on the remote server

sftp> mkdir newdirectory

Create a new directory on the local server

sftp> lmkdir newdirectory

7. Getting Help

You can find all SFTP commands with a short description by executing ‘help’ or ‘?’.

sftp> ?
