OSX manpage on "echo":
The echo utility writes any specified operands, separated by single blank
(` ') characters and followed by a newline (`\n') character, to the standard
output.
The following option is available:
-n Do not print the trailing newline character. This may also be
achieved by appending `\c' to the end of the string, as is done by iBCS2
compatible systems. Note that this option as well as the effect of `\c' are
implementation-defined in IEEE Std 1003.1-2001 (``POSIX.1'')
as amended by Cor. 1-2002. {*}Applications aiming for maximum
portability are strongly encouraged to use printf(1) to suppress the newline
character.{*}
Some shells may provide a builtin echo command which is similar or
identical to this utility. Most notably, the builtin echo in sh(1) does not
accept the -n option. Consult the builtin(1) manual page.
