Commands

The help page for the sudoku command is a good overview:

Usage: sudoku [OPTIONS] INPUT_FILE

  A command line tool for taking an input file encoding sudoku problems and
  writing their solutions to stdout.

  The input file consists of one sudoku problem per line, where each line is
  a string of integers in the range 0-9. A 0 denotes an empty location while
  all the other digits are filled cells. This string represents a walk
  through the grid from top to bottom and left to right.

  By default it exits with a message after encountering either an invalid
  problem or an unsolvable problem.

Options:
  -s, --size INTEGER  Size of the encoded sudoku problems. Defaults to 9.
  -i, --ignore        Silently ignores all errors. Writes blank lines for
                      unworkable problems.
  --help              Show this message and exit.

input_file

The input file format is described above in the help page.

So this board:

|0 9 0| |0,0,0| |0,0,6|
|0 0 0| |9,6,0| |4,8,5|
|0 0 0| |5,8,1| |0,0,0|

|0,0,4| |0,0,0| |0,0,0|
|5,1,7| |2,0,0| |9,0,0|
|6,0,2| |0,0,0| |3,7,0|

|1,0,0| |8,0,4| |0,2,0|
|7,0,6| |0,0,0| |8,1,0|
|3,0,0| |0,9,0| |0,0,0|

Would be encoded by this string:

090000006000960485000581000004000000517200900602000370100804020706000810300090000
