FTP – Used to Set File System Related Functions

The ftp command is a standard utility tool in Linux that is used to transfer files between a local host and a remote server. It is commonly used for downloading and uploading files to and from a remote server. The ftp command can be used in both interactive and non-interactive modes.


The syntax for using the ftp command is as follows:

ftp [options] [hostname]

Here, hostname refers to the name or IP address of the remote server that you want to connect to. If you don’t specify a hostname, the ftp command will attempt to connect to the local host.

Once you have established a connection to the remote server, you can use various commands to navigate through directories, upload and download files, and set file system related functions.

Here are some examples of how to use the ftp command:

To connect to a remote server:

ftp example.com

To upload a file:

put filename

To download a file:

get filename

To navigate through directories:

cd directoryname

To list the contents of a directory:



The ftp command provides several options that you can use to customize its behavior. Here is a table of the available options:

Option Description
-d Enables debugging mode
-i Disables interactive mode
-n Disables auto-login
-v Enables verbose mode
-p Enables passive mode
-s:filename Specifies a script file to execute

Troubleshooting Tips

Here are some common issues that you may encounter when using the ftp command, along with solutions:

  • Connection refused: This error occurs when the remote server is not accepting connections. Make sure that the hostname and port number are correct, and that the remote server is running and accessible from your network.
  • Login failed: This error occurs when the username or password that you provided is incorrect. Make sure that you have the correct credentials and that they are spelled correctly.
  • File transfer failed: This error occurs when the file that you are trying to upload or download is not available on the remote server, or when there is not enough disk space to complete the transfer. Make sure that the file exists and that you have permission to access it.


  • The ftp command is not secure, as it sends login credentials and file contents in plain text over the network. Consider using a secure file transfer protocol, such as SFTP or FTPS, instead.
  • The ftp command is included in most Linux distributions by default, so you don’t need to install any additional software to use it.
