RSH(1) | 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 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 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¶
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.
