I do not see your logic for 'non-zero' conversion.
Please define EXACTLY what you are doing for that conversion.

BTW 'non-zero' is any number 1,2,3...9 if you mean turn number > 1 into 1:

sed 's/[2-9]/1/g'  oldfile > newfile
3 
tr "[2-9]" "1" < infile
4 
$ ruby -ne 'print $_.gsub(/[2-9]/,"1")' file
0110
1010
1011
1011
1010
1001
1001
1010

or

$ ruby -ne 'print $_.tr("[2-9]","1")' file
