Remote shell
rsh [-dn] [-l username] host [command]
Neutrino
- -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 (the 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.
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're 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.

This utility needs to have the setuid (“set user ID”)
bit set in its permissions.
If you use
mkefs,
mketfs,
or
mkifs
on a Windows host to include this utility in an image,
use the perms attribute to specify its permissions explicitly,
and the uid and gid attributes to set the ownership
correctly. |
- /etc/hosts
- Hostname database.
The rsh utility requires the libsocket.so
shared library.
You can't use rsh to run an interactive command
such as vi; use rlogin instead.
