Yes and no. LC_NUMERIC is still at C, LC_CTYPE is set to UTF-8, but as
there are no non-ASCII symbols in that output it shouldn't matter,
right? For me, 819200 is smaller than 10485760 in pretty much all
locales. Why the hell is a numeric gnusort locale dependant? Why is -g
working anyway?
% locale
LANG=
LC_CTYPE=de_DE.UTF-8
LC_COLLATE="C"
LC_TIME="C"
LC_NUMERIC="C"
LC_MONETARY="C"
LC_MESSAGES="C"
LC_ALL=
% find a b c -ls | LC_ALL=C sort -nk7,7
12 64 -rw-r--r-- 1 uqs wheel 819200 Feb 10 09:13 c
10 64 -rw-r--r-- 1 uqs wheel 5242880 Feb 10 09:13 b
8 64 -rw-r--r-- 1 uqs wheel 10485760 Feb 10 09:13 a
Great, now I'm even more angry at sort(1) than before ...
