Sends a command to a remote host for execution, including a
command that invokes a remote shell script or remote command
procedure. Any command recognized by the remote host is valid.
When using the RSH command, consider the following:
o If you omit a command for remote execution, RSH initiates a
remote login session (see the RLOGIN command).
o If you specify the /PASSWORD qualifier, with or without a
value, RSH executes the REXEC facility.
DCL Format
RSH host [/EIGHTBIT ] [ remote_command ]
[ /ESCAPE_CHARACTER=character ]
[ /LOG_FILE=file ]
[ /[NO]LOWERCASE ]
[ /PASSWORD[=password] ]
[ /[NO]SYSERROR ]
[ /TERMINAL_SPEED=n ]
[ /TERMINAL_TYPE=type ]
[ /TRUNCATE_USER_NAME ]
[ /USER_NAME=remote_user_name ]
UNIX Format
rsh host [ -l remote_user_name ] [ remote_command ]
1 – Parameters
host
Required.
Remote host at which you want the command to execute.
remote_command
Optional. Default: none.
Command you are sending to the remote host for execution.
NOTE
The remote_command parameter must be the last item on the
command line.
2 – Qualifiers
2.1 /EIGHTBIT
Optional. Default: only 7-bit data is sent.
Accepts 8-bit data from the terminal and sends it to the remote
system.
2.2 /ESCAPE_CHARACTER
/ESCAPE_CHARACTER=character
Optional. Default: Tilde (~).
RSH escape character. This character lets you exit the RSH
process without entering the remote host's typical logout
sequence, such as LOGOUT or Ctrl/D.
Typing the escape character and a period (.) breaks the
connection with the remote host. For example:
remote> ~. (characters not echoed)
%RSH-S-LCLCLOSED, Local connection closed
local_vms>
2.3 /LOG_FILE
/LOG_FILE=file
Optional. Default: no logging.
Logs a copy of the output to the specified file. Output continues
to be directed to SYS$OUTPUT while it is being recorded in the
log file.
Not valid with /SYSERROR.
2.4 /LOWERCASE
/LOWERCASE
/NOLOWERCASE
Optional. Default: /LOWERCASE.
Sends your local user name to the remote host in lowercase
letters.
To send your user name in uppercase letters, do one of the
following:
o Specify /NOLOWERCASE.
o Enclose the user name in quotation marks ( " " ). (See the
/USER_NAME qualifier.)
To send your user name in mixed case, enclose it in quotation
marks ( " " ).
2.5 /PASSWORD
/PASSWORD[=password]
Optional.
Your password on the remote host.
Invokes the local REXEC facility that directs your RSH command
to the REXEC server on the remote host. This server does
authentication checking using the user name and password that
you specified on the RSH command line.
o Enclose the password in quotation marks ( " " ) if it is
lowercase or mixed case.
o If you omit password, RSH (REXEC) prompts you for one.
o Do not use this qualifier if you want to initiate an RLOGIN
session.
2.6 /
/[NO]SYSERROR
Optional. Default: /NOSYSERROR
Directs diagnostics to SYS$ERROR and output to SYS$OUTPUT.
When SYS$ERROR and SYS$OUTPUT both output to the same terminal,
the output might be garbled.
/NOSYSERROR directs output only to SYS$OUTPUT.
2.7 /TERMINAL_SPEED
/TERMINAL_SPEED=n
Optional. Default: your terminal's current speed.
Terminal speed passed to the remote host during an RLOGIN
session.
2.8 /TERMINAL_TYPE
/TERMINAL_TYPE=type
Optional. Default: your terminal's current type.
Terminal type passed to the remote host during an RLOGIN session.
2.9 /TRUNCATE_USER_NAME
/TRUNCATE_USER_NAME
Optional. Default: User names are not truncated
Abbreviates the user name sent to the remote host to eight
characters.
2.10 /USER_NAME
/USER_NAME=remote_user_name
-l remote_user_name (valid only on UNIX systems)
Optional. Default: same name on local host, but in lowercase
letters.
Your user name on the remote host. Specify this qualifier if your
user names on the remote host and local host are different.
To send your user name in uppercase letters, do one of the
following:
o Specify /NOLOWERCASE.
o Enclose the user name in quotation marks ( " " ).
To send your user name in mixed case, enclose it in quotation
marks ( " " ).
3 – Examples
1.$ RSH HENCE MAN CP
cp(1)
Name
cp - copy file data
Syntax
cp [ -f ] [ -i ] [ -p ] file1 file2
.
.
.
See Also
cat(1), pr(1), mv(1)
$
A user sends the man cp command to UNIX host hence for
execution.
2.$ RSH /USER_NAME=ROGERS DELPHI LS
OpenVMS user PHILIPS enters the ls command for execution at
remote UNIX host delphi. PHILIPS is accessing an account called
rogers.
3.$ RSH /PASSWORD=BLOOMER AVOC8N DIRECTORY
OpenVMS user PANTO sends the DIRECTORY command to remote
OpenVMS host AVOC8N. The remote directory listing is of PANTO's
home directory.
RSH /PASSWORD invokes REXEC, which authenticates PANTO's remote
password.
4.$ RSH /PASSWORD MAGIC CAT BUZZ.TXT
REXEC password: (password not echoed)<Return>
A user sends the cat command to host magic. /PASSWORD invokes
REXEC, which requires a password. Because the password was
omitted from the command line, REXEC prompts the user for it.
