XMESSAGE(1) User Commands XMESSAGE(1)

NAME

xmessage - display a message or query in a window (X-based /bin/echo)

SYNOPSIS

xmessage [ -buttons label1[:value1],label2[:value2], ... ] [ options
] -file filename
xmessage [ -buttons label1[:value1],label2[:value2], ... ] [ options
] message ...
xmessage [ -help | -version ]

DESCRIPTION

The xmessage program displays a window containing a message from the
command line, a file, or standard input. Along the lower edge of the
message is row of buttons; clicking the left mouse button on any of
these buttons will cause xmessage to exit. Which button was pressed
is returned in the exit status and, optionally, by writing the label
of the button to standard output.

The program is typically used by shell scripts to display information
to the user or to ask the user to make a choice.

Unless a size is specified, xmessage sizes itself to fit the message,
up to a maximum size. If the message is too big for the window,
xmessage will display scroll bars.

OPTIONS

These are the command line options that xmessage understands, in
addition to the standard ones listed in X(7).

-buttons button,button,...
This option will cause xmessage to create one button for each
comma-separated button argument. The corresponding resource
is buttons. Each button consists of a label optionally
followed by a colon and an exit value. The label is the name
of the Command button widget created and will be the default
text displayed to the user. Since this is the name of the
widget it may be used to change any of the resources
associated with that button. The exit value will be returned
by xmessage if that button is selected. The default exit
value is 100 plus the button number. Buttons are numbered
from the left starting with one. The default string if no
-buttons option is given is okay:0.

-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.

-file filename
File to display. The corresponding resource is file. A
filename of `-' reads from standard input. If this option is
not supplied, xmessage will display all non-option arguments
in the style of echo. Either -file or a message on the
command line should be provided, but not both.

-print This will cause the program to write the label of the button
pressed to standard output. Equivalent to setting the
printValue resource to TRUE. This is one way to get feedback
as to which button was pressed.

-center Pop up the window at the center of the screen. Equivalent to
setting the center resource to TRUE.

-nearmouse
Pop up the window near the mouse cursor. Equivalent to
setting the nearMouse resource to TRUE.

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

-help Print a usage message and exit.

-version
Print version info and exit.

WIDGET HIERARCHY

Knowing the name and position in the hierarchy of each widget is
useful when specifying resources for them. In the following chart,
the class and name of each widget is given.

RESOURCES

The program has a few top-level application resources that allow
customizations that are specific to xmessage.

file A String specifying the file to display.

buttons A String specifying the buttons to display. See the -buttons
command-line option.

defaultButton
A String specifying a default button by label.

printValue
A Boolean value specifying whether the label of the button
pressed to exit the program is written to standard output.
The default is FALSE.

center A Boolean value specifying whether to pop up the window at
the center of the screen. The default is FALSE.

nearMouse
A Boolean value specifying whether to pop up the window near
the mouse cursor. The default is FALSE.

timeout The number of seconds after which to exit with status 0. The
default is 0, which means never time out.

maxHeight (class Maximum)
The maximum height of the text part of the window in pixels,
used if no size was specified in the geometry. The default
is 0, which means use 70% of the height of the screen.

maxWidth (class Maximum)
The maximum width of the text part of the window in pixels,
used if no size was specified in the geometry. The default
is 0, which means use 70% of the width of the screen.

ACTIONS

exit(value)
exit immediately with an exit status of value (default 0).
This action can be used with translations to provide
alternate ways of exiting xmessage.

default-exit()
exit immediately with the exit status specified by the
default button. If there is no default button, this action
has no effect.

EXIT STATUS

If it detects an error, xmessage returns 1, so this value should not
be used with a button.
