rsh [options] [ -l username ] hostname [#port] command
or
remsh [options] [ -l username ] hostname [#port] command
| -n | Redirect the input of rsh to /dev/null. You sometimes need this option to avoid unfortunate interactions between rsh and the shell which invokes it. For example, if you are running rsh and invoke a rsh in the background without redirecting its input away from the terminal, it will block even if no reads are posted by the remote command. The -n option will prevent this. |
| +a | Enable authentication agent forwarding. |
| -a | Disable authentication agent forwarding. |
| +x | Enable X11 connection forwarding. |
| -x | Disable X11 connection forwarding. |
| -i file | Identity file for public key authentication |
| -F file | Read an alternative configuration file. |
| -t | Tty; allocate a tty even if command is given. |
| -v | Verbose; display verbose debugging messages. Equal to `-d 2' |
| -d level | Set debug level. |
| -V | Display version number only. |
| -q | Quiet; don't display any warning messages. |
| -f[o] | Fork into background after authentication. With optional 'o' argument, goes to "one-shot" mode. |
| -e char | Set escape character; ``none'' = disable (default: ~). |
| -c cipher | Select encryption algorithm. Multiple -c options are allowed and a single -c flag can have only one cipher. |
| -p port | Connect to this port. Server must be on the same port. |
| -P | Don't use priviledged source port. |
| -S | Don't request a session channel. |
| -L listen-port:host:port | Forward local port to remote address. Cause ssh to listen for connections on a port, and forward them to the other side by connecting to host:port. |

| +C | Enable compression. |
| -C | Disable compression. |
| -o 'option' | Process the option as if it was read from a configuration file. |
| -l username | Use username as the remote username instead of your local username. In the absence of this option, the remote username is the same as your local username. |

rsh +a comphope.com ls
Logs onto comphope.com after authentication (because using +a) and after authentication processes in this case the ls command and then disconnects.
The rsh cannot be used to run interactive commands. Instead use the rlogin command.
