The SuDoku command line app presents the graphical interface familiar from the applet.
SuDoku [-a boxesAcross] [-d boxesDown] [-i]
[-a boxesAcross] and
[-d boxesDown] options allow
the app to be started with a non-standard grid size. (Of course, it is possible
to change the grid size from within the app once it has started.) The default
values are three.
-i option stipulates that an initial grid should be read from
standard input. (In this case, the
will be ignored.) The initial grid should be entered in the format used by the
app's Copy button.
SuDoku starts an app that displays an empty 3x3 grid.
SuDoku -a 4 -d 4 starts an app that displays an empty 4x4 grid.
SuDoku < puzzle.txt starts an app that displays the puzzle stored
in the file
