For zsh the option n does a numeric sort of numbers in a string. It will do a lexicographical sort of the strings prefixing the number, followed by a numeric sort. This is handy for stuff like foo1 foo02 foo3. However, for a pure numeric string, this will fail when negative numbers are in use. a=( 10 8 -20 100 ); echo "${(@n)a}" this returns 8 10 100 -20. Be aware that the sorting of floats is just mimicked. It just does a numeric sort on the fractional part. You can see this with this example a=(1 1.11 1.2); echo ${(n)a} this returns 1 1.2 1.11 because 2 < 11
