Bash getopt - shift multiple parameters -

i have script launch checks on ubuntu machine.

i call script : ./script -f /tmp/file.txt --modules 001 002 003

all files 001, 002, etc... bash scripts.

the following main function problem :

main () { opts=`getopt -o hf:m: --long help,file:,modules: -n 'script.sh' -- "$@"`  eval set -- "$opts"     [ $# -eq 0 ] && echo "unknown options or parameters" && usage  while [ $# -gt 0 ];     case "$1" in             -f|--file)                file="$2"                shift                ;;             -h|--help)                usage                exit 1                ;;             -m|--modules)                modules="$2"                shift                ;;     esac     shift done  [ -z "$modules" ] && echo "no module specified" && usage } 

i $modules variable contains example 001 002 004.
tried different things shift, that's complicated..

ideally, if can use "$@" rest of script settings , great.

edit : ./script.sh -f /tmp/file.txt --modules "001 002 003" $modules variable contains "001 002 003" , example.

but have loop seems not iterate on args, on first... each $module contains "001 002 003".

for module in "$modules";      echo "importing module $module"     . modules/$module >> "$file"  done 

getopt can't arbitrary numbers of values, can pass modules list parameter usign " , later parser it:

./script -f /tmp/file.txt --modules "001 002 003" 

inside script can each individual value:

for module in $modules ;      echo $module done
