Definition: ``` `~ftp` is a command in Linux that allows a user to connect to FTP servers using the `telnet` protocol over a network interface (for example, Ethernet port or WiFi). It enables users to upload files and download them from remote FTP servers using their web browser. The command uses two arguments: - `~`: This is an abbreviation for "user domain". The server you want to connect to has this user name. - `ftp`: This is the local FTP protocol. This is a command-line interface (CLI) used by FTP clients to perform FTP operations on the server they are connecting to. The second argument, `port`, specifies the port number where the FTP server operates over an Internet connection. The default value is 21 for most Linux distributions, but you can change this if your system is set up to use a different port. ```
