if $OPTIND value start from 1 then i think "-b" $OPTIND should be "3" like sh but bash print "2"
set -- -a -bc hello world echo $OPTIND # sh, bash = 1 getopts abc opt "$@" echo $opt, $OPTIND # sh, bash = a, 2 getopts abc opt "$@" # bash = b, 2 <------ different from "sh" echo $opt, $OPTIND # sh = b, 3 getopts abc opt "$@" # sh, bash = c, 3 echo $opt, $OPTIND
