SM(6)

NAME
sm - Displays a short text fullscreen

SYNOPSIS
sm [ OPTIONS ] [ text | - ]

DESCRIPTION
Screen Message will display a given multi-line message as large as possible, fullscreen and black on white. You can specify the text either when launching sm, or edit it while the program is running.

After a short timeout, the text entry and the quit button will disappear, leaving nothing on the screen but the entered text. To continue entering text, just start typing or (left-)click anywhere on the screen.

To clear the displayed text, press Escape.

To invert the colors of the text and the background, press Ctrl-I.

To quit the program, press Ctrl-Q, or Escape twice, or click the "Quit"-button.

OPTIONS

[ text | - ]
    Text to display at start up. Defaults to ":-)". If "-" is passed to sm, it will read the text to display from the standard input, see REMOTE CONTROLLING SM.

-f, --foreground=colordesc
    Define a different color to use for the foreground of the text to display than black. The text string can be in any of the forms accepted by XParseColor; these include name for a color from rgb.txt, such as DarkSlateGray, or a hex specification such as #3050b2 or #35b.

-b, --background=colordesc
    Define a different color to use for the background of the text to display than white. For possible values, see above.

-i, --invert
    Switch the roles for foreground and background colors. Useful if you prefer white-on-black.

-n, --font=fontspec
    Define a different font to use than the default sans-serif font of your system. The fontspec be the complete name for a truetype font (like "DejaVu Sans" or "Bitstream Vera Serif") or just a short font family specification ("serif", "sans-serif").

-r, --rotate=rotation
    Rotates the display by rotation*90 degrees counter-clock-wise. So -r 1 rotates the display to the left, and -r 2 puts it upside down.

-a, --align=alignment
    Aligns the text centered (-a 0), left (-a 1) or right (-a 2).

--  (Double dash) End option parsing. This is used to be able to actually hand over text that starts of with an dash.

-h, --help
    This option will give you a short usage message summarizing the recognized options and quits.

-V, --version
    This prints the project name together with its version number quits.

REMOTE CONTROLLING SM
If sm is called with - as a command line argument, it will read the text to be shown from the standard input. It will read the input until it reaches the end of the file, or the form feed character \f, and show the input read so far at once. Newline characters at the beginning or the end are ignored. The input is assumed to be UTF-8 encoded (see utf8(7)).

This can be used to create automatic displays of changing data or similar tricks. For example, the following command will create a simple digital watch:

(while sleep 1; do date +%T; printf '\\f'; done) | sm -
