rsh

remote shell

Syntax:

 
rsh [-dn] [-l username] host [command]

Options:

-d

Using setsockopt(), turn on socket debugging on the TCP sockets used for communication with the remote host.

host

An Internet address specified in dot notation or a hostname.

-l username

Use the specified remote name (default remote name is the same as the local username). Authorization is determined as in rlogin.

-n

Redirect input from the special device /dev/null (see the ``Caveats'' section below).

command

The command to execute on remote host.

Description:

The rsh utility executes command on host. The standard input of rsh is copied to the remote command, and the standard output and standard error of the remote command are copied to rsh's standard output and standard error. Interrupt, quit, and terminate signals are propagated to the remote command; rsh normally terminates when the remote command does.

If you don't specify a command, you'll be logged in on the remote host via rlogin.

Shell metacharacters that aren't quoted are interpreted on the local machine; quoted metacharacters are interpreted on the remote machine. For example, the command:

 rsh otherhost cat remotefile >> localfile

appends remotefile to localfile, while:

 rsh otherhost cat remotefile ">>" other_remotefile

appends remotefile to other_remotefile.

Files:

/etc/hosts

Hostname database.

Caveats:

You can't use rsh to run an interactive command such as vi; use rlogin instead.
