/sys$common/syshlp/helplib.hlb RSH, Qualifiers, /PASSWORD  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /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.

    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.
