comm assumes its two inputs are sorted. Is it correct that it works in the same way as the merge sort algorithm?
If yes, can I use comm to merge-sort two sorted files?
Thanks.

comm acts like a single merge step of the merge sort algorithm, and further, produces separated output (in different columns), not combined output. Therefore it can't be used to "merge-sort" anything.
