Answer Posted / shh
rsh command
executes command on the specified hostname. To do so, it
must connect to a rshd service (or daemon) on the hostname
machine
rsh [username@]hostname [-DNn] [-l username] command
-D
enables socket debugging on the TCP sockets used for
communication with the remote host. This option also
displays the locuser and remuser being sent to rshd
-l username
specifies the remote user name to be used when executing
the command. This can also be specified by including
username@hostname on the command line
-N
does not generate a separate standard error stream. All
output is sent to standard output. This is useful when you
are running an interactive command
-n
redirects input from the special device /dev/nul.
