using getopt for both short and long options

Hi ,

I am using getopt for both short and long options as below

SHORTOPTS="a:c"
LONGOPTS="alpha:,charlie"
OPTS=$(getopt -o $SHORTOPTS --longoptions $LONGOPTS -n "$progname" -- "$@")
eval set -- "$OPTS"

while [ $# -gt 0 ]; do
case $1 in
-a|--alpha)
echo "-a or --alpha specified with "$2
shift 2
;;
-c|--charlie)
echo "-c or --charlie specified"
shift
;;
esac
done

if i run the above program like this ./sample1 --al hi or ./sample1 --cha

its taking --al as --alpha and --cha as --charlie

How to avoid this.It should take the option only if i give the entire option as --charlie and not --ch.Please help me.

Regards,
Padmini

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
