| 20 | .SH NAME |
| 21 | rsh \- remote shell |
| 22 | .SH SYNOPSIS |
| 23 | .B rsh |
| 24 | host |
| 25 | [ |
| 26 | .B \-l |
| 27 | username |
| 28 | ] [ |
| 29 | .B \-n |
| 30 | ] command |
| 31 | .br |
| 32 | host |
| 33 | [ |
| 34 | .B \-l |
| 35 | username |
| 36 | ] [ |
| 37 | .B \-n |
| 38 | ] command |
| 39 | .SH DESCRIPTION |
| 40 | .I Rsh |
| 41 | connects to the specified |
| 42 | .I host, |
| 43 | and executes the specified \fIcommand\fR. |
| 44 | .I Rsh |
| 45 | copies its standard input to the remote command, the standard |
| 46 | output of the remote command to its standard output, and the |
| 47 | standard error of the remote command to its standard error. |
| 48 | Interrupt, quit and terminate signals are propagated to the remote |
| 49 | command; \fIrsh\fP normally terminates when the remote command does. |
| 50 | .PP |
| 51 | The remote username used is the same as your local username, |
| 52 | unless you specify a different remote name with the |
| 53 | .B \-l |
| 54 | option. |
| 55 | This remote name must be equivalent (in the sense of |
| 56 | .IR rlogin (1)) |
| 57 | to the originating account; no provision |
| 58 | is made for specifying a password with a command. |
| 59 | .PP |
| 60 | If you omit |
| 61 | .I command, |
| 62 | then instead of executing a single command, you will be logged in |
| 63 | on the remote host using |
| 64 | .IR rlogin (1). |
| 65 | .PP |
| 66 | Shell metacharacters which are not quoted are interpreted |
| 67 | on local machine, while quoted metacharacters are interpreted on |
| 68 | the remote machine. |
| 69 | Thus the command |
| 70 | .PP |
| 71 | \ \ \ rsh otherhost cat remotefile >> localfile |
| 72 | .PP |
| 73 | appends the remote file |
| 74 | .I remotefile |
| 75 | to the localfile |
| 76 | .I localfile, |
| 77 | while |
| 78 | .PP |
| 79 | \ \ \ rsh otherhost cat remotefile ">>" otherremotefile |
| 80 | .PP |
| 81 | appends |
| 82 | .I remotefile |
| 83 | to |
| 84 | .I otherremotefile. |
| 85 | .PP |
| 86 | Host names are given in the file /etc/hosts. Each host |
| 87 | has one standard name (the first name given in the file), which |
| 88 | is rather long and unambiguous, and optionally one or more nicknames. |
| 89 | The host names for local machines are also commands in the directory |
| 90 | /usr/hosts; if you put this directory in your search path |
| 91 | then the |
| 92 | .B rsh |
| 93 | can be omitted. |
| 94 | .SH FILES |

| 99 | .DT |
| 100 | .SH SEE ALSO |
| 101 | rlogin(1) |
| 102 | .SH BUGS |
| 103 | If you are using |
| 104 | .IR csh (1) |
| 105 | and put a |
| 106 | .IR rsh (1) |
| 107 | in the background without redirecting its input |
| 108 | away from the terminal, it will block even if no reads |
| 109 | are posted by the remote command. If no input is desired |
| 110 | you should redirect the input of |
| 111 | .I rsh |
| 112 | to /dev/null using the |
| 113 | .B \-n |
| 114 | option. |
| 115 | .PP |
| 116 | You cannot run an interactive command |
| 117 | (like |
| 118 | .IR rogue (6) |
| 119 | or |
| 120 | .IR vi (1)); |
| 121 | use |
| 122 | .IR rlogin (1). |
| 123 | .PP |
| 124 | Stop signals stop the local \fIrsh\fP process only; this is arguably |
| 125 | wrong, but currently hard to fix for reasons too complicated to |
| 126 | explain here. |
