I'm trying to sort a file by second column, but in reverse order. I tried:

sort -k2n -r file.txt

The output is not in reverse order, so it seems -r is being ignored. I'm in CentOS.

Try to add a space after the -k and before the column position. e.g. something like below

sort -k 2n -r file.txt

I just needed to remove the "n" next to column number:

sort -k 2 -r file.txt
