NAME
   rsh - remote shell

SYNOPSIS
   rsh [-Kdnx] [-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 terminates
   when the remote command does. The options are as follows:

   -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.

   -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),

HISTORY
   The rsh command appeared in 4.2BSD.

BUGS
   If you are usingcsh(1) and put a rsh in the background without redirect-
   ing 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) orvi(1)) using rsh;
   userlogin(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.
