ChorusOS 5.0 System Administrator's Guide

Communicating with the Target Using `rsh`

For the ChorusOS operating system, commands that would in conventional UNIX systems be run through a shell are in fact run through rsh. The rsh command executes a command on a remote host, passing its input and receiving its output. When the ChorusOS 5.0 operating system image including the rsh feature is booted on the target machine, the C_INIT actor interprets the commands sent from the host through rsh. (See the rshd man page on your host). To see the list of the options available, type:

% rsh target help

where target is the target name or IP address.

The following information is displayed by the C_INIT actor:
