Query Json or Python Dictionary

Put following code in your home director bin folder , suppose file name is jqb

#!/bin/bash

# echo $#
# echo ${@}
# Parse Args


PROG_NAME=$(basename $0)

usage() {
    echo -e "***  PLEASE ENTER CORRECT VALUES FOR EACH FLAG  ***"
    echo -e "Usage:$PROG_NAME -f <filter node>"
    echo -e "For Example: sh $PROG_NAME -f  employees.0.id"
    echo -e "*** REFERENCE: ***"
    echo -e "          -f:  (filter), json filter"
    exit 1
}

# echo $#

# check if proper number of parameters are provided when script was executed
if [ $# != 2 ]; then
    usage

# echo $*

# check if -e and -k and -n parameters were provided
# if [[ ! "$*" =~ "-f" ]] || [[ ! "$*" =~ "-k" ]]|| [[ ! "$*" =~ "-n" ]] || [[ ! "$*" =~ "-d" ]]
if [[ ! "$*" =~ "-f" ]]
then
        usage
