This wasn't a criticism of anyone but rather an observation.
In the bash shell I have wondered about this sorting "anomaly" myself and so
looked it up this very day. As the simple (and pretty obvious, really) answer
was completely amenable to my intellectual powers, I was kind of enjoying
myself believing I'd mastered a trivial programming concept and wished to share
my joyful discovery with the group. That it happened to be the result of the
OP's explicit interrogation and so proves itself to be on-topic is a matter of
pure serendipity.
;-)
# sort numerically ascending
my @articles = sort {$a <=> $b} @files;
# sort numerically descending
my @articles = sort {$b <=> $a} @files;
The default must be to sort lexicographically.
