Passing long option arguments through getopts

[neville310]

I am trying to implement getopts into my Bash script for passing command line arguments, yet I am encountering difficulty with the actual syntax and long options support. The man for getopts did not include clear examples, so most examples came from other scripts on the net, which may not have the correct syntax. Please let know if long options are a possibility with getopts. Long options are the flags like --files or --verbose while shot options are -f or -v.

GETOPT=$(getopts -o fdp:uvh -n ${SCRIPTNAME} -- "$@")
if [ $? -ne 0 ]; then
  usage
fi

eval set -- "$GETOPT"


while [ "$1" != "" ]; do
    case "$1" in
        -f | --files )          FLAG_FILES="true"
                                ;;
        -d | --directories )    FLAG_DIR="true"
                                ;;
        -p | --preset )          shift
                                PRESET=$1
                                ;;
        -u | --undo )            FLAG_UNDO="true"
                                ;;
        -v | --verbose )        VERBOSE="yes"
                                ;;
        -h | --help )            usage
                                exit
                                ;;
        * )                       usage
                                exit 1
    esac
    shift
done

Bash return a /home/neville/bin/Filerenamer.sh: line 103: getopts: -o: invalid option. Please lead me to a syntax that support long options.
