File Transfer Protocol (FTP) and Secure File Transfer Protocol (SFTP) are two commonly used protocols for transferring files between a local machine and a remote server. In this article, we will discuss the differences between FTP and SFTP, when to use them, and how to use them with some examples.

FTP is a standard protocol that is widely used for transferring files over the internet. It allows users to upload and download files, create and delete directories, and perform other file management tasks. However, FTP is not a secure protocol as it transmits data in plain text, which makes it vulnerable to attacks.

SFTP, on the other hand, is a secure version of FTP. It uses SSH (Secure Shell) to encrypt the data being transferred, making it more secure than FTP. This makes SFTP a better choice for transferring sensitive information, such as financial data or personal information.

When deciding which protocol to use, it is important to consider the security of the data being transferred. If the data is sensitive and needs to be protected, SFTP should be used. However, if the data is not sensitive, FTP can be used.

To use FTP and SFTP, the command line interface (CLI) is typically used. The following are some examples of how to use FTP and SFTP commands in Linux.

FTP:

  1. To connect to a remote server using FTP, the command “ftp” is used followed by the server’s IP address or domain name. For example:
ftp ftp.example.com
  1. To upload a file to the remote server, the command “put” is used followed by the file name. For example:
put file.txt
  1. To download a file from the remote server, the command “get” is used followed by the file name. For example:
get file.txt

SFTP:

  1. To connect to a remote server using SFTP, the command “sftp” is used followed by the server’s IP address or domain name. For example:
sftp user@example.com
  1. To upload a file to the remote server, the command “put” is used followed by the file name. For example:
put file.txt
  1. To download a file from the remote server, the command “get” is used followed by the file name. For example:
get file.txt

In conclusion, FTP and SFTP are both commonly used protocols for transferring files between a local machine and a remote server. While FTP is widely used, SFTP is a more secure option as it encrypts the data being transferred. When deciding which protocol to use, it is important to consider the security of the data being transferred. The above examples demonstrate how to use FTP and SFTP commands in Linux to transfer files.
