Setting variable with getopts

[hancooper]

Have updated some things so I can use the following command
to set vb to 358, with the rest of the arguments being arg1 arg2

myfunc -v 358 arg1 arg2

And want to have

myfunc -v arg1 arg2

use default for vb

-----

These are the results

myfunc-status -v 238
arg: v
vb: 238                 # correct value set to vb
$@                      # correct, no arguments left

myfunc -v 238 arg1 arg2
arg: v
vb: 1             # incorrect, v must be 358
$@ 238 arg1 arg2  # incorrect arguments, including 358

getopt-status -v arg1 arg2
arg: v
vb: 1             # gives correct default
$@ arg1 arg2      # gives correct arguments


-- here is the code

myfunc ()
{

  local vb=123

  local OPTIND OPTARG
  local shortopts="Vuhv"
  while getopts $shortopts arg; do
    echo "arg: $arg"
    case $arg in
      # ........................................................
      ("V")
        printf "%s\n" "Version"
        return
        ;;
      ("u")
        printf "%s\n" "-V, -u, -h"
        printf "%s\n" "getopt-status --"
        return
        ;;
      ("h")
        printf "%s\n" "Prints status returned by getopt."
        printf "%s\n" "-V  Displays version"
        printf "%s\n" "-u  Displays usage"
        printf "%s\n" "-h  Displays help."
        printf "%s\n" "-v, -v NUM  Sets verbosity level."
        return
        ;;
      ("v")
        if [[ ${@:$OPTIND} =~ ^[0-9]+$ ]]; then
          vb=${@:$OPTIND:1}
          OPTIND=$((OPTIND+1))
        else
          vb=1
        fi
        ;;
    esac
  done

  local n="$((OPTIND-1))"
  shift "$n"

  echo "vb: $vb"
  echo "\$@ $@"

}
