       pmquery [-input] [all above options...]  [message...]

DESCRIPTION

       pmquery  provides  a  command-line-option  compatible  implementation of the xconfirm and xmessage tools,
       using a look-and-feel that is consistent with pmchart.  Several extensions to the  functionality  of  the
       original  tools  have  been  made,  in  order to improve their specific utility for pmchart, but wherever
       possible the original semantics remain.

       pmconfirm displays a line of text for each -t option specified (or a file when the -file option is used),
       and  a button for each -b option specified.  When one of the buttons is pressed, the label of that button
       is written to pmquery's standard output.  This provides a means  of  communication/feedback  from  within
       shell scripts and a means to display useful information to a user from an application.

       pmmessage  displays  a  window containing a message from the command line, a file, or standard input.  It
       additionally allows buttons to be associated with an exit status, and  only  optionally  will  write  the
       label of the button to standard output.

       pmquery  extends  the above tools to additionally support limited user input, as free form text.  In this
       -input mode, any text entered will be output when the default button is pressed.  A default text  can  be
       entered using the same mechanisms as the other tools.

       Command  line  options  are  available  to  specify  font style, frame style, modality and one of several
       different icons to be presented for tailored visual feedback to the user.

OPTIONS

       The available command line options are:

       -c, -center
            Center the window on the display.

       -nearmouse
            Pop up the window near the mouse cursor.

       -b button-name
            Displays a button with the label button-name.  If button-name is the empty  string,  the  button  in
            that  position  is  not  displayed.   If no -b options are present, the default is a button with the
            label Continue.  The exit status associated with button-name is zero.

       -B button-name
            Displays a button with the label button-name and specifies it as the button  to  be  activated  when
            enter is pressed.  The exit status associated with button-name is zero.

       -buttons button,button,...
            This  option will create one button for each comma-separated button option.  Each button consists of
            a label optionally followed by a colon and an exit value.  The exit value will be returned  if  that
            button  is  selected.   The  default exit value is 100 plus the button number.  Buttons are numbered
            from the left starting with one.

       -default label
            Defines the button with a matching label to be the default.  If not specified there is  no  default.
            The  corresponding  resource is defaultButton.  Pressing Return anywhere in the xmessage window will
            activate the default button.  The default button has a wider border than the others.

       -t message
            Displays message.  Any number of strings can be listed on the command line (each  must  be  preceded
            with the -t option).

       -file filename
            Displays  the file filename.  All -t options will be ignored.  A filename of `-' reads from standard
            input.

       -icon icontype
            Displays the icon icontype where icontype is one  of:  info,  error,  question,  warning,  critical.
            action  is  also accepted as a synonym for error for backward compatibility.  pmquery introduces the
            additional archive and host icon types as well as the original xconfirm types listed earlier.

       -font fontname
            Use fontname as the font.  This option is only available when using the X Window System.

       -header string
            Use string as the window title.

       -print
            This causes the program to write the label of the button pressed to  standard  output.   It  is  the
            default behaviour for pmconfirm and pmquery.

       -noprint
            This  causes the program to not write the label of the button pressed to standard output.  It is the
            default behaviour for pmmessage.

       -geometry geometry-string
            This provides the tool with an X-compatible geometry string  specification.   This  option  is  only
            available when using the X Window System.

       -useslider
            When displaying a file, always use a slider instead of determining automatically whether a slider is
            necessary.

       -noslider
            Do not create a slider, and clip text to the  window  size,  instead  of  determining  automatically
            whether a slider is necessary..

       -noframe
            Do not display a frame around the contents.

       -exclusive
            Grab the keyboard/pointer and do not allow further input until a button is pressed.

       -timeout secs
            Exit  with  status  0  after  secs  seconds  if  the  user  has  not  clicked  on a button yet.  The
            corresponding resource is timeout.

       -?, -h, -help
            Display usage message and exit.

EXAMPLES

       The following shell script will display a window with an information icon, asking the user a  yes  or  no
       question with "Yes" as the default.

        #! /bin/sh
        case `pmquery -t "Really power down?" -b No -B Yes -icon question
        in
          Yes) shutdown;;
          No) ;;
        esac

       A  second  example,  which prompts for a hostname then starts a terminal with an ssh session connected to
       the requested host.

        #! /bin/sh
        host=`pmquery -input -icon host -b Cancel -B OK \
                      -header "Remote Terminal - Secure Shell"
        [ "$host" = "Cancel" -o -z "$host" ] && exit
        gnome-terminal -e "ssh $host"

ENVIRONMENT

       pmquery is an excellent choice of utility for the PCP_XCONFIRM_PROG  Performance  Co-Pilot  configuration
       parameter (refer to pcp.conf(5) for details).

       Note  that  PCP_XCONFIRM_PROG  will  be  automatically  set  to pmquery inside tools like pmchart, unless
       PCP_XCONFIRM_PROG is already set in the environment.

EXIT STATUS

       If it detects an error, pmquery always returns 1, so this value should not be associated with  a  button.
       Unless -button option has not been used, the return code will be zero on success.
