rsh(1) -- Linux man page
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 terminates 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
Sx 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
-
SEE ALSO
rlogin(1),
HISTORY
The
rsh
command appeared in
BSD 4.2
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.
