Hi, http://pubs.opengroup.org/onlinepubs/9699919799.2016edition/utilities/sh.html the "sh" utility
has: > The following operands shall be supported: > > - > A single <hyphen-minus> shall be treated as the > first operand and then ignored. If both '-' and > "--" are given as arguments, or if other operands > precede the single <hyphen-minus>, the results are > undefined. That doesn't make sense to me. That seems to imply that in sh -c 'echo "$*"' sh - + / Or sh ./script + - / That "-" is treated as the first operand?!? Even if we have to understand it as: << "-" as a standalone argument shall be treated as the end of options and ignored like for "--">> The second part doesn't make sense to me. It would imply that the result is undefined for: sh ./script -f - file.txt (2 operands before "-") sh -u - "$script" -x -- *.txt sh -e -- "$script" -f - Both "-" and "--" given as argument. The whole point of "-" and "--" is to ensure what follows is safely treated as a list of operands. It defeats the purpose if one can't use "--" or "-" in that list of operands. Am I missing something? -- Stephane
