RSH(1)                      General Commands Manual                     RSH(1)

     rsh -- remote shell

     rsh [-46dn] [-l username] [-p port] host [command]
     rsh [-46dn] [-p port] username@host [command]

     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:

     -4            Use IPv4 addresses only.

     -6            Use IPv6 addresses only.

     -d            The -d option turns on socket debugging (using
                   setsockopt(2)) on the TCP sockets used for communication
                   with the remote host.

     -l username   By default, the remote username is the same as the local
                   username.  The -l option or the username@host format allow
                   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).

     -p port       Uses the given port instead of the one assigned to the
                   service ``shell''.  May be given either as symbolic name or
                   as number.  If no command is given, note that rlogin(1) is
                   started, which may need a different daemon (rlogind(8)
                   instead of rshd(8)) running on the server; you want to pass
                   the rshd(8) port number in that case.

     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.


     rcmd(1), rlogin(1), rcmd(3), hosts.equiv(5), rhosts(5), environ(7)

     The rsh command appeared in 4.2BSD.

     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.
