The locale specified by the environment affects sort order.
Set LC_ALL=3DC to get the traditional sort order that uses
native byte values.

and that's what you have run into.

To expound on Paul's answer:

> $ sort <foo
> t.co<= br> > tec.co<= /a>
> te.co

Let's run that with --debug to make it obvious:

$ printf '= t.co\nt= ec.co\nt= e.co\n' | sort --debug
sort: using =E2=80=98en_US.UTF-8=E2=80=99 sorting rules
t.co
____
tec.co ______
te.co
_____

and realize that en_US.UTF-8 is a locale where punctuation is ignored when = determining collation order (thus, 'tco' < 'tecco' < = 'teco' once you strip out the ignored '.').


I keep seeing these sort= "bugs" pop up, they seem to be very popular. At any point would = the default behavior be seen as needing change?

I&= #39;m not sure why I'd want to ignore special characters by default, fo= r example...

LC_ALL=C is not guaranteed to do that. There is no requirement that it use native byte values; on the contrary, it is required to not use native byte values in some circumstances (e.g., z/OS EBCDIC environments). This is a complicated area, unfortunately, and it's not something that can easily be condensed into a single line in a help message.
