Expanding on what RudiC has already said and replying to wisecracker's comment that this question is in my domain... If you're trying to write portable code, DO NOT use echo if you intend to invoke it with a first argument starting with <minus-sign> (-), with -- as an argument, or if any argument contains a <backslash> character (\).
The synopsis for echo in the standards is echo [string...] and the options section for echo in the standards says:
And then, unlike the description of any other utility in the standards, the description of the string operand is:
Except for the first paragraph of the above quote, this section is shaded and has an XSI margin tag which means that it applies only on systems that support the standard's XSI option (which means that the system supports all of the optional requirements needed for UNIX brand certification by The Open Group in addition to meeting all of the requirements needed for POSIX certification by the IEEE).
