But echo is not supposed to be print, it is supposed to be echo.
With echo interpreting characters anywhere in its args, there
is no sane way to do
unless you know what is in foo to start with, in which case there
isn't a lot of point printing it...
It sounds as if posix is doing something right, though arguments can be
made for even getting rid of -n and simply having echo echo its args to
stdout, with no additions, subtractions, ...
Pretending that an echo that knows about '\n' is rational is irrational.
ps: echo being echo is not BSD, it is original unix, from way way back.
