When calling script from another script in bash shell, how do I pass prefixed arguments to the called script from calling script?

Question

I have two scripts, in which script1 takes pre-fixed arguments as below(I'm using case, shift function to shift arguments and assign them as required) This is how I call script1 normally:

script1 --env [env] --db [db] --table [table] --location [location]

This is how I iterate through arguments in script1:

while [ "$#" -gt 0 ]
do
    case "$1" in
            --env | --environment)
                    shift
                    envie="$1"
                    ;;
            --db)
                    shift
                    db="$1"
                    ;;
            --table)
                    shift
                    table="$1"
                    ;;
           --tableLocation)
            shift
            tableLoc="$1"
            ;;

    esac
   shift
done

A table will be created here after the above code and I'm not specifying the code intentionally.

My second script calls the above script along with the parameters(dynamic) and I have trouble doing it. I'm trying it this way now. I'd like to invoke script1 and would like to consider the status if a table has been created or not( I think a return code would help here).

env=env1
db=database1
table=table1
tablelocation=tablelocation1
#call script1
`source script1 --env $env --db $db --table $table1 --tableLocation $tablelocation`

I'm seeing "command not found" error for this line(there are no syntax errors) Please let me know if there is a way to call script1 with prefixed arguments.

Answer 1

You do not need back ticks.

env=env1
db=database1
table=table1
tablelocation=tablelocation1
#call script1
script1 --env "$env" --db "$db" --table "$table1" --tableLocation "$tablelocation"

You use back ticks only, if you want to save the result.

Make sure that script1 is executable ( chmod +x ) and the directory is your PATH .

Your script only processes the first argument/value pair. You need to loop while there are still arguments left, eg something like:

while [[ $# -ge 1 ]]; do
    case "$1" in
            --env | --environment)
                    shift
                    envie="$1"
                    ;;
            --db)
                    shift
                    db="$1"
                    ;;
            --table)
                    shift
                    table="$1"
                    ;;
           --tableLocation)
                    shift
                    tableLoc="$1"
                    ;;
           *)
                    echo "invalid argument: $1"
                    exit 1
                    ;;
    esac
    shift  # shift out the consumed value
done

If you want to reuse your initial arguments, store them in an array before shifting them off:

initialArgs=( "$@" )

while [ "$#" -gt 0 ]; do
  : ...processing here...
  shift
done

source script1 "${initialArgs[@]}"
