TCP/IP is part of the underlying structure of your system. It allows you to communicate with another workstation or system merely by executing a command or program. Your system takes care of the rest.
The TCP/IP commands for end users can be grouped into the following categories:
| ftp hostname | Transfers files between a local and a remote host. |
| rcp file host:file | Transfers files between local and remote host or between two remote hosts. |
| tftp | Transfers files between hosts. |
| rexec host command | Executes commands one at a time on a remote host. |
| rlogin remotehost | Connects a local host with a remote host. |
| rsh and remsh remotehost command | Executes specified command at remote host or logs into the remote host. |
| telnet, tn and tn3270 hostname | Connects the local host with a remote host, using the TELNET interface. |
| finger or f user@host | Shows user information. |
| host hostname | Resolves a host name into an Internet address or an Internet address into a host name. |
| ping hostname | Sends an echo request to a network host. |
| rwho | Shows which users are logged in to hosts on the local network. |
| whois name | Identifies a user by user ID or alias. |
| talk User@Host | Converse with another user. |
