Re: converting array to string by quoting each element for eval

Please take a look and see if you have a better solution than the
following code without using quotearg.sh.

/tmp/tmp$ ll *
c d:
total 0
-rw-r--r-- 1 pengy wheel 0 2011-11-15 20:18:11 xx

a b:
total 0
-rw-r--r-- 1 pengy wheel 0 2011-11-15 20:18:15 yy
/tmp/tmp$ ../convert_args_to_string.sh 'a b' 'c d' -O "-type f -name '*'"
TEMP= -O '-type f -name '\''*'\''' -- 'a b' 'c d'
a b/yy
c d/xx
find 'a b' 'c d' -type f -name '*'
/tmp/tmp$ cat ../convert_args_to_string.sh
#!/bin/bash

TEMP=`getopt -o O: --long options: -n "${script_name}.sh" -- "$@"`

echo TEMP=$TEMP

if [ $? != 0 ] ; then printf "Terminating...\n" >&2 ; exit 1 ; fi

eval set -- "$TEMP"

abspath_script=`readlink -f -e "$0"`
script_absdir=`dirname "$abspath_script"`

while true ; do
  case "$1" in
    -O|--options)
      options="$2"
      shift 2
      ;;
    --)
      shift
      break
      ;;
    *)
      echo "Internal error!"
      exit 1
      ;;
  esac
done

arg_string=`quotearg.sh "$@"`

cmd="find $arg_string $options"
eval "$cmd"
echo $cmd
