NAME¶
rsh
—
remote shell
SYNOPSIS¶
rsh |
[ -Kdnx ]
[-k
realm ]
[-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 terminates when the remote
command does. The options are as follows:
-K
- The
-K
option turns off all Kerberos
authentication.
-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. Kerberos authentication is used, and authorization is
determined as in rlogin(1).
-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.
FILES¶
- /etc/hosts
-

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.
