One other thing:
POSIX itself says that echo's options are inherently non-portable. If
you are trying to use 'echo -n' or 'echo -e', you should REALLY consider
rewriting your script to use printf(1) instead, because then you won't
run into portability nightmares when your script is run on a different
platform (this is true whether you use the shell's builtin echo, or
whether you use 'env echo' to bypass the shell builtin and get whatever
is installed on PATH).
