Only with the XSI option (Unix), for POSIX, echo "\whatever" is unspecified. But as far as I can tell even with XSI, "echo '\123'" is unspecified as well, so dash is free to do what it likes here. > dash however additionally treats \num as an octal > sequence.

Given that the result of echo "\123" is unspecified, those scripts would not be POSIX and they are those to be fixed. -- Stephane -- To unsubscribe from this list: send the line "unsubscribe dash" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
