Ah, I missed the ‘variable number of fields’…

What is it you’re trying to show? Since the line in itself always is unique. If you only want to show the file name, you could use awk ‘{print $NF}’ to show the last field, end pipe that through uniq.

so:

awk ‘{print $NF}’ file | uniq (-c if you want to count them)

I don’t think either uniq nor sort have any notion of 'last field’ in a variable field situation.
