Ken, et al,
The
reason you get two different values is that in your first example, the list
if items is "1,2,3,4,5," and ends in the item delimiter (,). Since there is
nothing that follows the item delimiter, it is ignored, and returns 5 items.
The second example gives you ",1,2,3,4,5" so there are 6 items (nothing's
ignored).
From my perspective, the focus of JB's issue is not the presence or
absence of a terminating comma, but if (the number of items of
"1,2,3,4,5,") is 5, why does (sort items of "1,2,3,4,5," ascending numeric)
sort 6 values instead of 5?
It appears the sort command's definition of an item is different than the
"number of items of" syntax.
