What are the uses of the Linux telnet command?

The Telnet command is used to remotely log in to another computer and execute commands or operations on the remote computer. It is a text-based protocol that allows a Telnet client to connect to a Telnet server on a remote computer.

The usage of the Telnet command is as follows:
telnet [options] [hostname] [port]

Common options include:
-4: Connect using the IPv4 protocol.
-6: Connect using the IPv6 protocol.
-l : Specify the username to use when logging into the remote computer.
-p : Specify the port number for the connection.
-r: Specify data to record and display during the connection.

For example, to connect to the Telnet server on the remote host example.com using telnet, you can use the command: telnet example.com

If the Telnet server on the remote host is not using the default port 23, you can specify the port number using the -p option:
telnet example.com 8080

After successfully connecting to the Telnet server on the remote host, you can input commands and perform operations. To exit the Telnet session, you can use Ctrl+] in the telnet command, followed by typing quit.
