How to Use the Linux ftp Command

FTP (File Transfer Protocol) is a network protocol used for transferring files from one computer system to another. Even though the safety of FTP tends to spark a lot of discussion, it is still an effective method of transferring files within a secure network.

In this tutorial, we will show you how to use the ftp command to connect to a remote system, transfer files, and manage files and directories.

How to use the ftp command in Linux

  • Access to a local system and a remote FTP server (learn how to install an FTP server on Ubuntu, CentOS 7, or Raspberry Pi).
  • A working Internet connection.
  • Access to the terminal window.

IMPORTANT: FTP traffic is not encrypted and is thus considered unsafe. It is not recommended to transfer files over the Internet using FTP. To learn more about secure alternatives to FTP, have a look at our articles on SFTP and TSL vs. SSL.

Linux ftp Command Syntax

The Linux ftp command uses the following basic syntax:

The IP is the IP address of the system you are connecting to.

The options available for the ftp command are:

FTP Command Options Description
-4 Use only IPv4.
-6 Use only IPv6.
-e Disables command editing and history support.
-p Uses passive mode for data transfers, allowing you to use FTP despite a firewall that might prevent it.
-i Turns off interactive prompting during multiple file transfers.
-n Disables auto-login attempts on initial connection.
-g Disables file name globbing.
-v Enables verbose output.
-d Enables debugging.

The ftp command connects you to a remote system and initiates the FTP interface. The FTP interface uses the following commands to manage and transfer files to the remote system:
