Since Bash doesn't support two-dimensional arrays, you can limit your columns length by some big enough constant value ( in this example 100 ) and then index the array with i and j, or maybe write your own get() and set() methods to index the array properly like I implemented for example ( see Sample output ).
For example for i=0 and j=0...99 you'll pick up one of 100 elements in the range [0,99] in the one-dimensional array.
For i=1 and j=0...99 you'll pick up one of 100 elements in the range [100,199].
And so on.
Be careful when using this, and remember that in fact you are always using one-dimensional array.
If you can do better, submit your command here.
