Hey Corona688, thanks for the reply.

Ok, that makes sense about there being a security risk for that...

The reason why I wanted to do that was because, like I mentioned in the OP, I have a bunch of
differnet possibilites for the optional command line args. Which in turn means a ton of differnt
combinations of arguments are possible. And because of that I would need a bunch of if statemnts
to check for these combinations (which is what I originally had)...

For example: Lets say that some of Optional Arguments are:
$option='start|stop|restart|status|add' --> Required Argument so $option will be on the executing line no matter what
command="..."
comment="..."
--restart
etc...

So for just these three args I would need all these If Statements...

Code:

if [[ $option =~ add ]]
 then
    if [ $comment -eq 1 ]
     then
        if [ $restart_option -eq 1 ]
         then
            /path/to/script/myExpect_script $ip_address $username $password $option command="..." comment="..." --restart --sshed
        elif [ $restart_option -eq 0 ]
         then
            /path/to/script/myExpect_script $ip_address $username $password $option command="..." comment="..." --sshed
        fi
    elif [ $comment -eq 0 ]
     then
        if [ $restart_option -eq 1 ]
         then
            /path/to/script/myExpect_script $ip_address $username $password $option command="..." --restart --sshed
        elif [ $restart_option -eq 0 ]
         then
            /path/to/script/myExpect_script $ip_address $username $password $option command="..." --sshed
    fi
fi

As you can see in the code above, this can get pretty messy, and that's only 3 of the options
that I'm checking in this example...

Since you said there's a security risk in doing it the way I was suggesting. Maybe I could just parse that option
that was passed from bash (i.e. $exe_command_args) and split it on whitespace, or something like that from
within the Expect Script..?

Thanks Again,
Matt

ttk::checkbutton(3tk)						 Tk Themed Widget					     ttk::checkbutton(3tk)

__________________________________________________________________________________________________________________________________________________

NAME

       ttk::checkbutton - On/off widget

SYNOPSIS

       ttk::checkbutton pathName ?options?
_________________________________________________________________

DESCRIPTION

       A  ttk::checkbutton  widget is used to show or change a setting.  It has two states, selected and deselected.  The state of the checkbutton
       may be linked to a Tcl variable.

STANDARD OPTIONS

       -class		     -compound		  -cursor
       -image		     -state		  -style
       -takefocus	     -text		  -textvariable
       -underline	     -width

       See the ttk_widget manual entry for details on the standard options.

WIDGET-SPECIFIC OPTIONS
       Command-Line Name:-command
       Database Name:  command
       Database Class: Command

	      A Tcl script to execute whenever the widget is invoked.

       Command-Line Name:-offvalue
       Database Name:  offValue
       Database Class: OffValue

	      The value to store in the associated -variable when the widget is deselected.  Defaults to 0.

       Command-Line Name:-onvalue
       Database Name:  onValue
       Database Class: OnValue

	      The value to store in the associated -variable when the widget is selected.  Defaults to 1.

       Command-Line Name:-variable
       Database Name:  variable
       Database Class: Variable

	      The name of a global variable whose value is linked to the widget.  Defaults to the widget pathname if not specified.

WIDGET COMMAND

       In addition to the standard cget, configure, identify, instate, and state commands, checkbuttons support the  following	additional  widget
       commands:

       pathname invoke
	      Toggles between the selected and deselected states and evaluates the associated -command.  If the widget is currently selected, sets
	      the -variable to the -offvalue and deselects the widget; otherwise, sets the -variable to the -onvalue Returns  the  result  of  the
	      -command.

WIDGET STATES

       The  widget  does not respond to user input if the disabled state is set.  The widget sets the selected state whenever the linked -variable
       is set to the widget's -onvalue, and clears it otherwise.  The widget sets the alternate state whenever	the  linked  -variable	is  unset.
       (The alternate state may be used to indicate a "tri-state" or "indeterminate" selection.)

STANDARD STYLES

       Ttk::checkbutton widgets support the Toolbutton style in all standard themes, which is useful for creating widgets for toolbars.
