AIX -/usr/bin/expect shows output Don't know why.
Hi,

I have been programming with the expect program for a while now and have create a series of menu driven checks for the operations team. One thing I have noticed is that I call a remote script and pass parameters and this is display on the screen....for example.
Within the script

#!/usr/bin/expect
set timeout 2
#password passed into script
set pw1 [lrange $argv 0 0 ]
set pw2 ]lrange $argv 1 1 ]
#set off messages
log_user 0
#swap to user
spawn su - user
expect "Password:"
send "$pw1\r"
expect "$"
---- no messages up to this point
send "/usr/local/nik/bin/program $pw2\r"

I get ....

</program password
returned on the screen
I can't understand why when log_user 0 is enabled

Any one any ideas? Of course I don't want every one seeing a password ....

Thanks Nik.

install-menu

install-menu(1) 					      Debian GNU/Linux manual						   install-menu(1)

NAME

       install-menu - Process a menu method and generate the menu files for a window manager or a menu-aware application.

DESCRIPTION

       update-menus(1) computes the list of menu entries and passes it in turn to the menu methods in /etc/menu-methods/. The task of a menu meth-
       ods is to generate menus for a specific window manager.	install-menu provides a generic and customizable way to do that. The documentation
       of the install-menu definition language is available in the Debian Menu manual, a local copy being available in /usr/share/doc/menu/html.

SYNOPSIS

       install-menu [-vh] [--remove] <menu-method>

       Read menu entries from stdin in update-menus --stdout format and generate menu files using the specified menu-method.

       Normally used in menu method scripts as #! /usr/bin/install-menu.

OPTIONS

       -h,--help
	      Show the help message and exit.

       --remove
	      Remove the menu files instead of generating them.

       -v,--verbose
	      Output messages about what the program is doing.

COPYING

       install-menu is distributed under the term of the GNU General Public License version 2, or (at your option) any later version.
