BASH: getopts with default parameters value

Question

I\'ve got another bash-script problem I simply couldn\'t solve. It\'s my simplified script showing the problem:

while getopts \"r:\" opt; do
case $opt in

  r)
          


        

Answer 1

This works for me:

#!/bin/bash

while getopts "r" opt; do
case $opt in

  r)
    fold=/dev
    dir=${2:-$fold}

     echo "asdasd"
  ;;
esac
done

Remove the colon (:) in the getopts argument. This caused getopt to expect an argument. (see here for more information about getopt)
