-n option is to redirect the output to dev/null
rsh -n -l username IPaddr ". ~/.profile >/dev/null 2>/dev/null; YOUR COMMAND HERE"
---------- Post updated at 01:19 PM ---------- Previous update was at 01:17 PM ----------
-n Redirect the input of rsh to /dev/null. You
sometimes need this option to avoid unfor-
tunate 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 blocks even if no
reads are posted by the remote command. The
-n option prevents this.

netkit-rsh
RSH(1) BSD General Commands Manual RSH(1)
NAME
rsh -- remote shell
SYNOPSIS
rsh [-Kdnx] [-k realm] [-l username] host [command]
DESCRIPTION
Rsh executes command on host.
Rsh copies its standard input to the remote command, the standard output of the remote command to its standard output, and the standard error
of the remote command to its standard error. Interrupt, quit and terminate signals are propagated to the remote command; rsh normally termi-
nates when the remote command does. The options are as follows:
-K The -K option turns off all Kerberos authentication.
-d The -d option turns on socket debugging (using setsockopt(2)) on the TCP sockets used for communication with the remote host.
-l By default, the remote username is the same as the local username. The -l option allows the remote name to be specified. Kerberos
authentication is used, and authorization is determined as in rlogin(1).
-n The -n option redirects input from the special device /dev/null (see the BUGS section of this manual page).
If no command is specified, you will be logged in on the remote host using rlogin(1).
Shell metacharacters which are not quoted are interpreted on local machine, while quoted metacharacters are interpreted on the remote
machine. For example, the command
rsh otherhost cat remotefile >> localfile
appends the remote file remotefile to the local file localfile, while
rsh otherhost cat remotefile ">>" other_remotefile
appends remotefile to other_remotefile.
FILES
/etc/hosts
SEE ALSO
rlogin(1), kerberos(3), krb_sendauth(3), krb_realmofhost(3)
HISTORY
The rsh command appeared in 4.2BSD.
BUGS
If you are using csh(1) and put 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. If no input is desired you should redirect the input of rsh to /dev/null using the -n option.
You cannot run an interactive command (like rogue(6) or vi(1)) using rsh; use rlogin(1) instead.
Stop signals stop the local rsh process only; this is arguably wrong, but currently hard to fix for reasons too complicated to explain here.
