According to POSIX.1-2008: The echo utility shall not recognize the "--" argument in the manner specified by Guideline 10 of XBD Section 12.2; "− −" shall be recognized as a string operand. It is not possible to use echo portably across all POSIX systems unless both −n (as the first argument) and escape sequences are omitted. The echo utility has not been made obsolescent because of its extremely widespread use in historical applications.
