How to pass Named Parameter in Shell Script-CodePudding

Below is the shell script using getopts

#!/bin/bash

while getopts "USER:PWD:JOBID:PROJECTID:" flag
do
         case "${flag}" in
                USER) TEST_USER=${OPTARG};;
                PWD) TEST_PWD=${OPTARG};;
                JOBID) TEST_JOBID=${OPTARG};;
                PROJECTID) TEST_PROJECTID=${OPTARG};;
         esac
       
done
echo "USER: $TEST_USER";
echo "PWD: $TEST_PWD";
echo "JOBID: $TEST_JOBID";                  
echo "PROJECTID: $TEST_PROJECTID"; 

Continue of script i have not put here and if above commands work fine then my issue solve

And Here what im running output in terminal, Which one is a correct way to get output command

./getopts.sh [email protected] -PWD=xxxxxx -JOBID=8a809e2496 -PROJECTID=80e2ea54b231f
OR
./getopts.sh [email protected] PWD=xxxxxx JOBID=8a809e2496 PROJECTID=80e2ea54b231f
