[Solved] Counting specific characters within each field
Hello,

I have a file like following:
ALB_13554 1 1 1
ALB_13554 1 2 1
ALB_18544 2 0 2
ALB_18544 1 0 1

This is a sample of my file, my real file has 441845 number of fields. What I want to do is to calculate the number of 1 and 2 in each column using AWK, so, the output file looks like this:

3 1 #for the first column which has three 1 and one 2
1 1
3 1

The zeros should be ignored.

Thank you very much for your help in advance.
