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 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

       /etc/hosts

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.
