'comm' requires that the input files be sorted. These are not sorted, because "~" comes after "5" in the ascii order. You can test this for yourself with something like: $ echo -e "5~30\n55~40" | sort 55~40 5~30 It works when you use "," because that character comes before the digits in the ascii order. Run your input files through 'sort' before passing them to 'comm'.
