That whole paragraph has more problems. Firstly, the phrase "non-option-argument" is ambiguous: it can be parsed as (non-option)-argument as intended, or as non-(option-argument). Secondly, it doesn't properly account for arguments that are option-arguments. Thirdly, it uses "option-argument" when it means an argument that is an option. Finally, it refers to "--" as a "special option", which it is not. I think the most awkward complications could be avoided simply by referring to operands. Here is a suggested replacement paragraph: When the end of options is encountered, the getopts utility shall exit with a return value greater than zero; the shell variable OPTIND shall be set to the index of the first operand, or the value "$#"+1 if there are no operands; the name variable shall be set to the <question-mark> character. Any of the following shall identify the end of options: the first "--" argument that is not an option-argument, finding an argument that is not an option-argument and does not begin with a '-', or encountering an error. |
