When I use sort -n -c on a specified column in a file sort reports an error and then stops if two numbers are exactly the same. I want the sort to find actual sort errors, i.e. number (n+1) < number(n). This negates the use of sort -n -c on large files to find files that are actually out of order. Any way to fix this ?
