rsh

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.

     -k    The -k option causes rsh to obtain tickets for the remote host in
           realm instead of the remote host's realm as determined by
           krb_realmofhost(3).

     -l    By default, the remote username is the same as the local username.
           The -l option allows the remote name to be specified.  Kerberos au-
           thentication 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).

     -x    The -x option turns on DES encryption for all data exchange.  This
           may introduce a significant delay in response time.

     If no command is specified, you will be logged in on the remote host us-
     ing rlogin(1).

     Shell metacharacters which are not quoted are interpreted on local ma-
     chine, 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.
