here's something I don't remember ever noticing before, and I'm wondering how many errors I've made over the years because of it. the GNU sort utility default is to respect case; you have to give it the -f option to make it case-insensitive. at least, that's what the manpage says. in actuality:

jcomeau@aspire:~/Downloads$ echo -ne 'F9\nf7\nF5\nf0\n' | sort
f0
F5
f7
F9

to make it do the expected:

jcomeau@aspire:~/Downloads$ echo -ne 'F9\nf7\nF5\nf0\n' | LC_ALL=C sort
F5
F9
f0
f7

my locale is set to en_US.UTF-8, nothing abnormal. so WTAF?
