RSH(1)                    BSD General Commands Manual                   RSH(1)

NAME
     rsh -- remote shell

SYNOPSIS
     rsh [-46dn] [-l username] [-t timeout] host [command]

DESCRIPTION
     The rsh utility executes command on host.

     The rsh utility copies its standard input to the remote command, the standard output of the remote com-mand command
     mand 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    Turn on socket debugging (using setsockopt(2)) on the TCP sockets used for communication with the
           remote host.

     -l username
           Allow the remote username to be specified.  By default, the remote username is the same as the
           local username.  Authorization is determined as in rlogin(1).

     -n    Redirect input from the special device /dev/null (see the BUGS section of this manual page).

     -t timeout
           Allow a timeout to be specified (in seconds).  If no data is sent or received in this time, rsh
           will exit.

     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
     /etc/auth.conf

     rshd(8)

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 ee(1) 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.
