Easily Inspect Arguments Passed to a bash Script

Have you ever had problems with bash scripts? Not understanding why they're not working? Sometimes, you just need to echo the arguments to make sure they're being interpreted correctly:

	#!/usr/bin/env bash
	#-------------------------------------------------------------------------------
	#
	# print_args - easily inspect arguments passed to a bash script
	#
	# sources:

	#-------------------------------------------------------------------------------
	function print_args {
	echo "arguments:"
	local ii=1
	for arg; do
	printf " \$%u: '%s'\n" "$ii" "$arg"
	((ii++))
	done
	}
	# usage:
	#
	# $ print_args 3 "3.a" "hello world"
	# arguments:
	# $1: '3'
	# $2: '3.a'
	# $3: 'hello world'
	function example {
	echo "printing arguments passed to 'example'..."
	printargs "$@"
	echo "...done."
	printf "\$2 = %s\n" "$2"
	}
	# example:
	#
	# $ example "a b" 5.5 ho-ho
	# printing arguments passed to 'example'...
	# arguments:
	# $1: 'a b'
	# $2: '5.5'
	# $3: 'ho-ho'
	# ...done.
	# $2 = 5.5
