rsh

     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 terminates
     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

HISTORY
     The rsh command appeared in 4.2BSD.

BUGS
     If you are using csh(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.
