Remote shell (rsh) commands, which are among the r commands, can be used to execute commands on remote hosts without being logged into them. No password is required from the executing host to execute the command. However, command execution cannot be done interactively
, i.e. only for predefined parameter entries. With an rsh command used in remote maintenance, a program can be activated and the status messages queried on a remote computer on which the daemon process of RemoteShell must be running.
