NAME

6       rsh - remote shell

SYNOPSIS

9       rsh host [ -l username ] [ -n ] command
10       host [ -l username ] [ -n ] command
11

DESCRIPTION

13       Rsh connects to the specified host, and executes the specified command.
14       Rsh copies its standard input to the remote command, the standard  out‐
15       put  of  the  remote  command  to its standard output, and the standard
16       error of the remote command to its standard error.  Interrupt, quit and
17       terminate  signals  are  propagated to the remote command; rsh normally
18       terminates when the remote command does.
19
20       The remote username used is the same as your local username, unless you
21       specify  a  different remote name with the -l option.  This remote name
22       must be equivalent (in the sense  of  rlogin(1C))  to  the  originating
23       account; no provision is made for specifying a password with a command.
24
25       If  you  omit  command, then instead of executing a single command, you
26       will be logged in on the remote host using rlogin(1C).
27
28       Shell metacharacters which are not  quoted  are  interpreted  on  local
29       machine,  while  quoted  metacharacters  are  interpreted on the remote
30       machine.  Thus the command
31
32          rsh otherhost cat remotefile >> localfile
33
34       appends the remote file remotefile to the localfile localfile, while
35
36          rsh otherhost cat remotefile ">>" otherremotefile
37
38       appends remotefile to otherremotefile.
39
40       Host names are given in the file /etc/hosts.  Each host has  one  stan‐
41       dard  name (the first name given in the file), which is rather long and
42       unambiguous, and optionally one or more nicknames.  The host names  for
43       local  machines  are  also commands in the directory /usr/hosts; if you
44       put this directory in your search path then the rsh can be omitted.

BUGS

54       If you are using csh(1) and put a rsh(1C)  in  the  background  without
55       redirecting  its input away from the terminal, it will block even if no
56       reads are posted by the remote command.  If no  input  is  desired  you
57       should redirect the input of rsh to /dev/null using the -n option.
58
59       You  cannot  run  an  interactive command (like rogue(6) or vi(1)); use
60       rlogin(1C).
61
62       Stop signals stop the local rsh process only; this is  arguably  wrong,
63       but currently hard to fix for reasons too complicated to explain here.
