unix sort algorithm implementation
What sorting algorithm(s) is/are used in the unix sort command? Insertion/quicksort/etc.?
Solution 1:
If you are referring to GNU sort, it implements a variant of the merge sort algorithm.
The coreutils are open source, so feel free to download them and take a look.
Solution 2:
The relevant POSIX standard doesn't dictate what algorithm to use, so implementations are free to choose what they like.
