pattern decomposition

[opert]

Hello,

I have patterns like this:

0100100110010001

I would like to break up this and should get the following patterns:

0000100110010001
0100000010010001
0100100100000001
0100100110010000

So you can imagine the original one as blocks of 4's

0100 1001 1001 0001

and I should leave every blocks once (in a permutation way so that consider the empty block as being 0's everywhere).

Can anyone help me to solve this?

something like this ?

awk '{for(i=1;i<length;i+=4)print substr($0,1,i-1)"0000"substr($0,i+4)}' /path/to/patterns

Hope This Helps, PH.
