Hi power user,

I have data as follows

aa bb
bb aa
aa bb
bb aa
bb cc
cc bb
bb cc
zz ll
ll zz
zz ll

and I want the output to be like this:

aa bb 4
cc bb 3
zz ll 3

So, althrough the data in the column are arranged in a different order, they will be considered the same data. Is there any awk script which could do that? Tx
