rsh

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

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 termi-
     nates 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
	   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).

     -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 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

SEE ALSO

     rlogin(1), kerberos(3), krb_sendauth(3), krb_realmofhost(3)

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.
