RSH(1) BSD General Commands Manual RSH(1) NAME
rsh -- remote shell SYNOPSIS
rsh [-Kdnx] [-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: -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. -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.

rlogin(1), 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. Linux NetKit (0.17) August 15, 1999 Linux NetKit (0.17)

RSH(1C) RSH(1C) NAME
rsh - remote shell SYNOPSIS
rsh host [ -l username ] [ -n ] command host [ -l username ] [ -n ] command DESCRIPTION
Rsh connects to the specified host, and executes the specified command. 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 remote username used is the same as your local username, unless you specify a different remote name with the -l option. This remote name must be equivalent (in the sense of rlogin(1C)) to the originating account; no provision is made for specifying a password with a com- mand. If you omit command, then instead of executing a single command, you will be logged in on the remote host using rlogin(1C). Shell metacharacters which are not quoted are interpreted on local machine, while quoted metacharacters are interpreted on the remote machine. Thus the command rsh otherhost cat remotefile >> localfile appends the remote file remotefile to the localfile localfile, while rsh otherhost cat remotefile ">>" otherremotefile appends remotefile to otherremotefile. Host names are given in the file /etc/hosts. Each host has one standard name (the first name given in the file), which is rather long and unambiguous, and optionally one or more nicknames. The host names for local machines are also commands in the directory /usr/hosts; if you put this directory in your search path then the rsh can be omitted. FILES
