Linux awk descending sort does not work

I have two files to sort.

The command I used was:

cat first-in.txt | 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 > first-out.txt

cat second-in.txt | 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 > second-out.txt

The questions are:
I need to sort correctly in descending order because now only file 2 is sorted correctly, but file 1 is not sorted correctly.

I

wonder what mistake I made

file

All files are here including output are here

Thanks in advance.

I guess you mean it’s wrong :

4.2.4
4.2.3
4.2.20
4.2.2

You want 4.2.20 to be higher than all of that, right?

You can work around this by changing the -k parameter of sort to treat all fields as numbers:

.... -k 1,1nr -k 2,2nr -k 3,3nr -k 4,4nr -k 5,5nr ....
