Linux sort correctly

Hi, I have 2 test files that I need to sort with the same command. File 1: [login to view URL] The command I'm using is: cat [login to view URL] | awk '{print $2}' | cut -d '/' -f 3 | cut -d '^' -f 1 | sort -b -t . -k 1,1nr -k 2,2nr -k 3,3r -k 4,4r -k 5,5r | uniq > [login to view URL] cat [login to view URL] | awk '{print $2}' | cut -d '/' -f 3 | cut -d '^' -f 1 | sort -b -t . -k 1,1nr -k 2,2nr -k 3,3r -k 4,4r -k 5,5r | uniq > [login to view URL] ISSUE: I need to sort CORRECTLY in descending order, because right now, only file 2 is sorting correctly, but file 1 is not sorting correctly. I need that both files should sort correctly, in descending order.
