Using getopts to process long and short command line options

Question

I wish to have long and short forms of command line options invoked using my shell script.

I know that getopts can be used, but like in Perl, I have not

Answer 1

Another way...

# translate long options to short
for arg
do
    delim=""
    case "$arg" in
       --help) args="${args}-h ";;
       --verbose) args="${args}-v ";;
       --config) args="${args}-c ";;
       # pass through anything else
       *) [[ "${arg:0:1}" == "-" ]] || delim="\""
           args="${args}${delim}${arg}${delim} ";;
    esac
done
# reset the translated args
eval set -- $args
# now we can process with getopt
while getopts ":hvc:" opt; do
    case $opt in
        h)  usage ;;
        v)  VERBOSE=true ;;
        c)  source $OPTARG ;;
        \?) usage ;;
        :)
        echo "option -$OPTARG requires an argument"
        usage
        ;;
    esac
done
