Sadly, this proves very little about Linux's behavior. glibc's idea
of en_US involves some very complicated multi-pass sort rules.
AFAICT from the FreeBSD sort(1) man page, FreeBSD defines en_US
as "same as C except case-insensitive", whereas I'm pretty sure
that underscores and other punctuation are nearly ignored in
glibc's interpretation; they'll only be taken into account if the
alphanumeric parts of the strings sort equal.
Achilleas didn't mention the glibc version, but based on the kernel
vintage mentioned I guess that must be the "old" (pre 2.28) glibc
sorting. In 2.28 they did a big sync-up with ISO 14651, while FreeBSD
follows the UCA, a closely related standard[1]. I think newer
Linux/glibc systems should agree with FreeBSD's libc in more cases
(and also agree with ICU).
Thank you Thomas , our linux's glibc is on version : 2.19-18+deb8u10, we
need to upgrade on so many levels.
